DIY Raspberry Pi: AirPi climate sensor
Project: AirPi climate sensor
By: Alyssa Dayan 16 & Tom Hartley, 17
1 x Pi
1 x humidity and temperature sensor
1 x air pressure sensor
1 x general air-quality sensor, carbon-monoxide sensor
1 x nitrogen-dioxide sensor
1 x school chemistry lab to test and calibrate sensor levels
How do we know that today's kids care about the environment?
Check out A-level students Dayan and Hartley, who have put together a fully functional weather and air-quality device.
Connecting a series of pollution and climate sensors to the Pi and writing a Python programme to recognise and track these levels, the duo then uploaded the results onto a website that others can add their local data, too.
Soon, enthusiasts from around the world were using the instructions on Hartley and Dayan's website to build their own AirPi's, and adding their data to the duo's nascent weather network.
"Out of the blue people from places such as Ho Chi Min City, Vietnam, were contacting us to join up," says Dayan.
