Description	Building an Airrohr and participating in http://luftdaten.info/
Author(s)	Severin, Matthias

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.

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

Results

• The ESP provides a web server with the current data: http://feinstaubsensor-1251799.local/ (works only within the Lab's Wifi
• Live-Tracking the Luftdaten-Map: http://muenchen.maps.luftdaten.info/#11/48.1400/11.5600 our ID is 3655
