Particle Sniffer with GPS and Sharp Sensor

April 28, 2013

Using the Sharp dust sensor, I got Particle Sniffer to collect GPS and particle data.

We’ll probably just write out a string like below to the USB memory stick every 15 seconds or so; whatever Melissa requires.

Sn ID is the Sniffer ID, which will be different for each PS device. Particle Data is particle density (after applying a linear algorithm to interpret the Sharp output) and the rest of the values come from the GPS.
