Measure All The Things - 1 - Pollution Sensor (PMS5003 particle sensor)

The beginning of a series. "Measure all the things" is a journey through home sensing on a sensible budget. In this episode we have a go at measuring air pollution / dust / air quality using a cheap but apparently fairly well thought out particle sensor - the PMS5003 - and arduino. Let's see if it works!
