Seeed Studio Dust Sensor for PPD42NS Air Purifier System, Grove System

The Seeed studio dust sensor kit is designed to indicate the air quality in an environment by measuring the dust concentration. This kit has an integrated PPD42NS dust sensor. The particulate matter level (PM level) in the air is measured by counting the low pulse occupancy time (LPO time) in a given time unit. LPO time is proportional to PM concentration. This sensor uses a counting method to measure dust concentration, not weighing method, and the unit is pcs/L or pcs/0.01cf.
