Dust'Air

The idea is to create an autonomous device, mounted on a bike, which would map the pollution in a city, for example for comparing different cycle path.

For this we use a GPS module and a particle monitor, both interfaced via serial lines.
A Raspeberry Pi (v2) and a power bank have been re-used from a former project. I also added a DHT22 sensor for temperature, it may be of some interest.
For now the design is far from being compact, mainly due to the size of the Raspberry and of the power bank.

The software part and the spec. of the sensors are stored here:

A visualization tool based on jupyter notebooks is available in the data directory of the github project
