Documentation for the airpi sender

Airpi sender

The main program is https://github.com/ellak-monades-aristeias/system-of-traffic-lights-and-raspberry-pi-for-air-quality-estimation/blob/master/src/raspberryServer/opt/trafficAirpi/sendMeasurements.py. It runs the airpi software, parses its output, extracts the parts that are interesting and sends them to the central-server using the http protocol.
