Measuring air pollution wthi low-cost sensors

In a metal oxide sensor (resistive sensor, semiconductor) gases in the air react on the sensor surface and modify its resistance. photo ionization detector ionises volatile organic compounds and measures the resulting electrical current. Optical particle counters detect particulate pollution by measuring the light scattered by particles.

Monitor air quality with a Raspberry Pi - Raspberry Pi

· 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. Air is the very stuff we breathe. It’s about 78% nitrogen, 21% oxygen, and 1% argon, and then there’s the assorted ‘other’ bits and pieces – many of which have been spewed out by humans and our related machinery.
