The OK Lab Stuttgart has developed a kit to measure air pollution, especially particulate. It is easy to build, provides the necessary firmware and gathers the data on a geographical map for everyone to follow.
More information on http://luftdaten.info/
We built one for the lab and put it in front of our building. A second one is mounted inside above the 3D printing shelves.
Sensors
- SDS011 to measure the particulate
- DHT22 for the temperature
Building
It needs more or less:
- a NodeMCU (ESP8266) so that their firmware is running out of the box (support automatic update of the firmware).
- some pipes from the Baumarkt and
- a USB / Power-Plug
Instructions to assemble can be found here: https://github.com/opendata-stuttgart/meta/wiki
Code for the Firmware can be found here: https://github.com/opendata-stuttgart/sensors-software/tree/master/airrohr-firmware
