Revisions
First prototype
Severin bought a kit full of different Grove sensors a while back, to build a device to measure air quality and other things.
Currently, it only runs an Arduino sketch to output measurements to the serial port. But the ultimate idea is to build something similar to AirCasting.
Station at CCCamp15
Reviving the idea, a small weather & air quality station was built at CCCamp15, with these parts. It used not all sensors, but measured UV, temperature, humidity, air pressure, and PM2.5, uploading all that to OpenSenseMap. Code is here: https://github.com/tiefpunkt/airqualitystation
Sensors
Home Prototypes
One
In order to test the particulate matter sensor, a prototype with a Shinyei PM sensor, a DHT22, a fan, and an ESP8266 was build (TODO: hackaday.io link)
Test boards
Not having made a decision on the sensor yet, two test boards were built, one for the Shinyei sensor, and one for the Sharp sensor. The Shinyei "won" the comparison by great lengths.
Software
Currently, very simple setup using InfluxDB and Grafana. The idea however is to have a map with all the sensors, similar to opensensemap.org, but not as limited. Ideally something that's similar to meshviewer (the platform used by Freifunk): https://github.com/ffnord/meshviewer
