Welcome to the wonderful world of Engineering humour The HATs allow for easy customisation and the magical ability to turn a Raspberry Pi for all sorts of citizen projects. from Adafruit_IO import Client Also, hotter and drier weather driven by climate change leads to more frequent and more significant bushfires in summer, another primary air pollution source in Australia. furniture and textiles can pollute your apartment or house over several years. I hope you found the same joy from learning a little about the world of electronics and citizen science data collection. Heres why you can trust us. aio.send(AirQuality25pm, pmtwofive) . We picked the SDS011 for a couple of reasons. We used a Tupperware box with a hole cut in the bottom mounted on the wall, with a USB cable carrying power out via a window. Its about 78% nitrogen, 21% oxygen, and 1% argon, and then theres the assorted other bits and pieces many of which have been spewed out by humans and our related machinery. 1. Adafruit_IO.errors.RequestError: Adafruit IO request failed: 404 Not Found not found API documentation can be found at https://io.adafruit.com/api/docs That said, the flow was ~90% the same. Let us know if you try it. How does the particular make-up of your area affect your air quality? As you can see, they have great data coverage in Europe but could use additional sensors in other parts of the world. The W in the name means that this model comes with networking in-built, which is important for connecting to wifi and sending data to Sensor Community. However, I remember distinctly from my childhood an annual phenomenon called The Smog when asthmatics and those with respiratory issues were told to stay indoors. These pins allow access to power and input/output control signals from the device itself, making attaching custom hardware to the computer trivial. I will show you how easy it is to build a device that can monitor air quality and contribute the data collected to Sensor.community (formerly Luftdaten), a global network of DIY environmental sensors. You might want to choose a more geographically relevant name. Thankfully, a few innovations over the past 10 years have lowered the barrier to entry, meaning that its relatively easy to create basic electronics projects and have a lot of fun along the way. However, its useful for recording outdoor air quality and sending data on the particulate matter to Sensor.community allowing us to measure, A computer to set up and configure the Raspberry Pi, Micro USB Power supply for your Raspberry Pi (an old phone USB charger should do, but you can also get an. By creating straightforward and hardy miniaturised computers that fit on a single circuit board (about the size of the palm of your hand), the device became popular with makers who wanted an easy way to experiment with sensors and robotics. sensor HAT created by Pimoroni. Its faster to install, runs faster, and easy access remotely from our computer. I hope you found the same joy from learning a little about the world of electronics and citizen science data collection. If youre collecting data for a study, then you should discard any readings when the humidity is above this. Once youre monitoring your PM2.5 data, what should you look out for? Use your data for personal use or to add to global air quality research. aio.send(AirQuality10pm, pmten) Drawn to anything with electricity and flashing lights, he spent his childhood building computers and mostly improving them. Air is the very stuff we breathe. The World Health Organisation air quality guideline stipulates that PM2.5 not exceed 10g/m3 annual mean, or 25g/m3 24-hour mean; and that PM10 not exceed 20g/m3 annual mean, or 50g/m3 24-hour mean. The easiest method of calibration is to test it against an accurate sensor, and most cities here in the UK have monitoring stations as part of Defras Automatic Urban and Rural Monitoring Network. This sends output via a binary data format on a serial port. However, that doesnt mean that air quality isnt a concern in Australia; substantial pollen blooms during springtime and extreme weather create risky scenarios such as. 1.1 Visit https://www.raspberrypi.org/software/, 1.2 Install the Raspberry Pi Imager onto your computer, 1.3 Insert your micro SD card into your computer via an SD Card reader, 1.4 Open the Raspberry Pi Imager and click Choose OS.

So we can have some fun and learn together Ive chosen a path that is on the more accessible end but still requires some DIY electronics, building, and coding. Firstly, its cheap enough for many makers to be able to buy and build with. The next piece of hardware were going to use is. However, even these might not be safe. We then use the join method of this which takes a list and joins it together using this empty string as a separator. Why is air quality important to you whats the quality like where you live? Instructions: https://luftdaten.info/en/construction-manual/ :). during the dry season to clear land for palm oil and paper plantations. We chose Adafruit IO because its easy to use, lets you share visualisations (in the form of dashboards) with others, and connects with IFTTT to perform actions based on values (ours tweets when the air pollution is above legal limits). You. The Raspberry Pi is a revolutionary device for the world of makers. 2.1 [If Required] Attach your header to the Raspberry Pi Zero W. I used a Pi Zero W Starter Kit for convenience, but note that this kit requires some basic soldering to attach the Pi Zero W board header. When following the guide on registering your device, note that Luftdaten is now called Sensor Community and has a slightly updated site. Were interested in bytes 2 and 3 for PM2.5 and 4 and 5 for PM10. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Here at Curiosity Saves the Planet, we hope to inspire your curiosity to learn about our planet and the environment. This code takes care of communication with the sensor, and sets up a simple server for monitoring on your home network. Particulate Matter Sensor added to the Enviro+. I found that removing two screws from the right side of the Pibow case (dont worry, it wont open) and using a wire clipper to strip off some of the bend protection on my micro-USB cable (we actually do want it to bend here) helped me make it fit snugly. . Similarly, clean air is important to our health and wellbeing. Enviro+ Hat is on and looking fashionable. As the empty string contains nothing, this returns a byte string that just contains our two numbers. However, its useful for recording outdoor air quality and sending data on the particulate matter to Sensor.community allowing us to measure PM 2.5 and PM10 data. Unlike the rest of our project, you can feel free to be creative here. and airing out your place is essential to keeping you in good health? As you can see, many factors influence the air quality in your region. Have you tried to correlate particulate matter with VOCs concentration? The second phase of our project involves assembling the Raspberry Pi, Enviro + HAT, and case if you have one. We found, for example, that the glue gun produced huge amounts of PM2.5, and well be far more careful with ventilation when using this tool in the future. When hes not working, Ganesh can be found tinkering with electronics projects, creating his next mix as a bedroom DJ, and training his attack-cat Comrade. When I type in this line import serial, time I get the following bash: import: command not found. You can check this project for some comparison: https://www.hackster.io/damancuso/air-quality-measurements-and-analysis-in-a-spreadsheet-9fa887

I would recommend purchasing this model, which comes with the Header (the rows of pins) pre-installed, so you dont need to do any soldering at all! If you want it outside, itll need a waterproof case (but include some way for air to get in). Now youve got your monitoring station up and running, how do you know that its running properly? What is the official Air Quality (AQI) where you live? All the sensors we need for this project are conveniently packaged into a small circuit board ready to slot on top of the Raspberry Pi Zero W convenient, right? So, if you live in any of the other continent It would be super cool if you set one of these up and added your data. First, it reads ten bytes of data over the serial port exactly ten because thats the format that the SDS011 sends data in and sticks these data points together to form a list of bytes that we call data. Singapore is a highly developed city that enjoys better air quality than most Asian cities. 4.2 Register your sensor on Sensor Community, Use the number on the LCD while running: python luftdaten.py. Standard advice for locating your sensor is that it should be outside and four metres above ground level. The b creates an empty string of bytes. The USB-to-serial connector makes it easy to connect the sensor to a computer. You will need to push a little but double-check to make sure its oriented the right way (the HAT should sit over the board) and with all pins aligned and dont force it! aio.send(AirQuality25pm, pmtwofive) Once you have the Command Prompt of the Raspberry Pi up on your terminal, just resume the Pimoroni Getting Started guide at the step called Installing the Enviro+ Python library. Environmental education should be fun, easy to understand, and give you practical ways to connect with nature, so we can come together to enact simple changes to save the planet. Both the hackAIR and InfluencAir projects have compared the readings from these sensors with more expensive, better-tested sensors, and the results have come back favourably. Perhaps theres an issue with the sensor, or perhaps theres a problem with the code. The Raspberry Pi Foundation makes this super easy. Open-source hardware like the Raspberry Pi, make getting started a breeze. Most of us know inherently how vital a healthy diet is. You can see more details athsmag.cc/DiYPfgand hsmag.cc/Luhisr. By collecting an accurate picture of air quality trends in your area, you can help researchers looking for a robust dataset and also use this data yourself to advocate for improvements with your local representatives. raise RequestError(response) The one caveat is that the results are unreliable when the humidity is at the extremes (either very high or very low). Youll need a free account, which you can sign up for onthe Adafruit IO website youll need to know your Adafruit username and Adafruit IO key in order to run the code below.

Theyre grouped together based on their size the most important, from a health perspective, are those that are smaller than 2.5 microns in width (known as PM2.5), and PM10, which are between 10 and 2.5 microns in width. What factors contribute to air quality (good or bad) in your home region? the 404 is likely because you havent created the feeds so adafruit is trying to put them on your particular page but cant find them. Run the build command to build the docker images. File /home/pi/weather-station/novaPM_sensor.py, line 14, in Simply insert the SD Card, power up the device, wait a couple of minutes, and then SSH into raspberrypi.local (or the IP address of the device you found earlier). Notify me of follow-up comments by email. Now, because we installed Raspberry Pi OS Lite, there are a couple of additional configuration steps we want to do to preconfigure the device so we can remotely access it when we power it up.

If you didnt do so in the previous step, ensure your Raspberry Pi is powered off and attach the Particulate Matter Sensor the cable only goes into the socket in one orientation, so use that gentle force once more. You can store your data wherever you like on the SD card, or upload it to some cloud service. Tom's Hardware is part of Future US Inc, an international media group and leading digital publisher. These modules are called HATs, which stands for Hardware Attached on Top.

The Smog was a human-created issue caused by farmers in nearby Indonesia doing mass burnoffs during the dry season to clear land for palm oil and paper plantations. According to the WHO, air pollution kills an estimated 7 million people every year. Heres how to do it. I mightvtry that too. The Raspberry Pi is a revolutionary device for the world of makers. We divide the result by ten, because the SDS011 returns data in units of tens of grams per metre cubed and we want the result in that format aio.send is used to push data to Adafruit IO. The next piece of hardware were going to use is the Enviro + Air Quality HAT sensor HAT created by Pimoroni. Secondly, its been reasonably well studied for accuracy.

Congratulations, youve (hopefully) successfully assembled the hardware and softwarePat yourself on the back. The first command is the feed value you want the data to go to. Then I have a project for you! Since I recommended installing the headless Lite version of Raspbian OS, youll need to SSH into your device for this next part (the last part of, Once you have the Command Prompt of the Raspberry Pi up on your terminal, just, resume the Pimoroni Getting Started guide, , which takes the existing sensor package and adds a script that lets us talk to Sensor Community. you can buy HackSpace mag directly from us, https://luftdaten.info/en/construction-manual/, https://openschoolsolutions.org/measure-particulate-matter-with-a-raspberry-pi/, http://www.airqualityontario.com/aqhi/locations.php, https://www.hackster.io/damancuso/air-quality-measurements-and-analysis-in-a-spreadsheet-9fa887. Most of this can be found at a DIY store, so pick what works for you, but Ill show you what I did later on. In 2013, a large survey published in The Lancet found a 7% increase in mortality with each 5 micrograms per cubic metre increase in particulate matter with a diameter of 2.5 micrometres (PM2.5).. self._handle_error(response)

I was thrilled to find this project and share it with you. If you think this project looks too easy or too hard, know there are many other options from building and programming everything yourself to buying an off-the-shelf solution that just needs power and the internet. return self.create_data(feed, payload) Can I install more than one sensor at a time and get seperate results for each? Fortunately, using a SDS011 sensor, a Raspberry Pi and a bit of software, I can create a simple home air quality monitor. Add a sensor and some Python 3 to your Raspberry Pi to keep tabs on your local air pollution, in the project taken from Hackspace magazine issue 21. ** Make sure when you push the HAT down onto the header pins to use gentle force. Since its early years, the Raspberry Pi has gone through four iterations of the design, resulting in a larger format B model, and a compact Zero model. Oryou can buy HackSpace mag directly from us worldwide delivery is available. HackAIR has a formula for attempting to correct for this, but its not reliable enough to neutralise the effect completely. Carbon dioxide is obviously an important polluter for climate change, but there are other bits we should be concerned about for our health, including particulate matter. I know it was super easy to work with and a lot of fun to make. Sorry, I'm a noob! This project will use the incredible Raspberry Pi platform and an Enviro+ Air Quality monitor HAT as a sensor package. 6.3 Click on Show on Map to see the air quality data for your local area, centred on your device. The Envirohat looks pretty neat! The Raspberry Pi runs a Linux operating system and has networking, video, audio, and USB built-in so you can plug it into power, a screen, monitor, and keyboard and write programs for it from the device itself! Interesting project!! Stick around until the end for ways to connect and engage with him. For those who want to dive deeper to contribute to citizen science and improve air quality, lets get making. Would love to see the air quality readings! Singapore is a highly developed city that enjoys better air quality than most Asian cities.

Were doing great, hope you all are well too Ganesh. Most of us know inherently how vital a healthy diet is. You can change the filter on the bottom right to see various data like PM 2.5, PM 10 and Air Quality Index pretty sweet, eh? 3. The SDS011 is only rated to work up to 70% humidity.

Youll see a graph. Without it, you could still make a pretty fun sensor package. time.sleep(10), It keeps giving me a : So I encourage you to search for modifications that work for you.

You may want to take precautions to prevent birds/animals from building nests in there too. What was your favourite part of this project? If you want historical data, youll need to sign up for the Plus option (which stores data for 60 days), or use an alternative storage method. I'm having the same issue - currently running Raspberry Pi 3 (B+) - not headless. Does the idea of building your own electronics to analyse the environment around you sound exciting? My wife, Susanna, helped a bit while learninging to Solder for the first time. We will be building an at-home air quality monitor using Raspberry Pi and Enviro +. If youre able to successfully run the examples at the end (my favourite is the one that powers the little screen with data), then you are almost done! The Raspberry Pi is a low-cost computing device designed by an open-source foundation looking to promote basic computer science teaching in developing countries. , which will plug and play with our Enviro + board. Make sure its waterproof and aimed downwards so air can still get in, but water cant. Run the server to start taking measurements. Locating your monitor near your workbench will give you an idea of what youre actually inhaling useless for any environmental study, but useful if you spend a lot of time in there. In addition the above guide doesnt cover the fact that the sensor has some inbuilt default behavior you may need to override to stop you getting inaccurate readings. Share your progress and answers to the questions with me in the comments, I look forward to reading them. may want to take precautions to prevent birds/animals from building nests in there too. The one caveat is that the results are unreliable when the humidity is at the extremes (either very high or very low). I would recommend, purchasing this model, which comes with the Header (the rows of pins) pre-installed. This server shows running measurements for the last 30 minutes, but could be easily adapted to do more. (formerly Luftdaten), a global network of DIY environmental sensors. Are you talking about the one from the Raspberry Pi Blog? Human-driven industrial activity (e.g., factories, transportation, agricultural burning) and climate change (e.g., larger, more frequent fires) are further exacerbating the problem. Nice! You can install this by entering the following commands in a terminal: Youll now need to open a text editor and enter the following code: This does a few things. This step is optional, you can also use a case, but I like the open air look of the system. Micro SD Card (8Gb is plenty) to hold the operating system of your Raspberry Pi. You can now run your sensor with: There are a variety of particulate sensors on the market. I discuss both options below. pmten = int.from_bytes(b.join(data[4:6]), byteorder=little) / 10 Here in Germany, some rental contracts require you to open your windows for 10 minutes a day to get Frische luft for good health. I discuss both options below. Since we wont be using our Raspberry Pi as a traditional computer, the Lite version is better. We convert these from bytes to integer numbers with the slightly confusing line: pmtwofive = int.from_bytes(b.join(data[2:4]), byteorder=little) / 10. from_byte command takes a string of bytes and converts them into an integer. aio.send(twofive, pmtwofive) Before we dive into the project, I want to share a bit of background on the technology were working with and why we live in such an exciting time for citizen science and technology projects. pmten = int.from_bytes(b.join(data[4:6]), byteorder=little) / 10 We set out to monitor our environment to see how concerned we should be about our local air. leads to more frequent and more significant bushfires in summer, another primary air pollution source in Australia. I hope that once youve experienced how simple it is to create an air quality sensor, youll move on to other citizen science projects too! File /home/pi/.local/lib/python3.7/site-packages/Adafruit_IO/client.py, line 254, in create_data If mounting the sensor inside a component, make sure the air inlet port is connected to the outside of the case. You can find your local station here. I was thrilled to find this project and share it with you. We used kingswoodtwofive and kingswoodten, as the sensor is based in Kingswood. There are a variety of particulate sensors on the market. **Note: When assembling the case, it might be a little challenging to push the Raspberry Pi with its power cable into the pipe, especially if you used the same case and pipe. See their website for more details: hsmag.cc/DhKaWZ. PVC Drainpipe, zip ties, velcro command straps, and duct tape to mount your air quality monitor outside. Its unlikely youll be able to find the same type of piping in all parts of the world, so just find some PVC drainpipe that you can assemble to hold the device. The metal pegs along the top are for easy attachment of HATs. Now that we know our Raspberry Pi and air quality sensors are working, its time to contribute to the world of science! y other countries have equivalent public networks. NY 10036. Air pollution kills about 7 million people a year. Australia, being sparsely populated and with lower industrial activity than other countries, enjoys relatively low pollution from human-made sources. When following the guide on registering your device, note that Luftdaten is now called Sensor Community and has a slightly updated site. If youve ever wanted to automate some of the lights in your home, set up a wildlife camera, or create a weather station, we live in a time where technology has made these projects easy to do for almost anyone. You can see more details at. Particles of PM2.5 are particularly bad for your health if they contain toxic substances. We will need to ensure that we put our device into a weather-proof container while still allowing air sampling access. Nowadays, Ganesh spends his time focused on the intersection of technology and culture as a Google product manager. I followed all the steps but when I try to run the code I am receiving the following errors: Traceback (most recent call last): If youre just interested in reading data occasionally, this is a perfectly fine way of using the sensor, but we want a continuous monitoring station and we didnt want to leave our laptop in one place, running all the time. Clone the repository with example code. The wiring for this project is just about the simplest well ever do: connect the SDS011 to the Raspberry Pi with the serial adapter, then plug the Raspberry Pi into a power source. Ive lived in Singapore, Australia, and Germany, three countries with very different air quality characteristics, and three different experiences for me as an asthmatic. on attaching your Enviro + Air Quality Hat and testing its functions. While there are official sensors in most major towns and cities, the effects can be very localised around busy roads and trapped in valleys. Think of it as the same way a computer has a hard drive. Save my name, email, and website in this browser for the next time I comment. PM stands for particulate matter and the number after is the amount of micrometers, 2.5 or 10. Before getting started on the code, we also need to set up a data repository. I have a soldering iron at home and was keen to dust off my skills, but if youre not comfortable working with solder (its like a mix of hot glue and welding), then I recommend just buying the pre-assembled Pi Zero WH or the Starter Kit and a Hammer Header kit to make this step much more manageable. Make sure your SD Card is inserted (as you wont be able to get to it again quickly once you build the case), I assembled the Pibow Zero W as per this guide. Being compact means it is less powerful, saving energy and space (but still more than powerful enough for our needs). Unless there is no other option, we would caution against using crowdsourced data for calibration, as these sensors arent themselvescalibrated. Sounds very interesting. I will show you how easy it is to build a device that can monitor air quality and contribute the data collected to. This may take a bit of time depending on your Raspberry Pi. Before we dive in, let me give you a bit of background as to why Im so passionate about this project, because if nothing else, I would love to convince you that understanding the quality of the air around you is so important. from Adafruit_IO import Client There are links to articles in this comment thread that cover that. Many other countries have equivalent public networks.

When I was two years old, I was diagnosed with Asthma, a chronic condition Ive lived with all my life. In general, air quality in the southern hemisphere is better due to it being less populated than the northern hemisphere. For this part, were following this guide from Pimoroni, which takes the existing sensor package and adds a script that lets us talk to Sensor Community. The other attraction of the Raspberry Pi is the community of independent hardware vendors who make add-ons called HATs. However, we dont have a string of bytes, we have a list of two bytes, so we first need to convert this into a string. You may see a flashing red light, but if not, dont worry. Make sure to do this before you place outside. I hope that once youve experienced how simple it is to create an air quality sensor, youll move on to other citizen science projects too! 4.1 Register an account with Sensor Community.
