Grove - Dust Sensor (PPD42NS）

This Dust Sensor gives an indication of the air quality in an environment by measuring the dust concentration. 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 can provide reliable data for air purifier systems; it is responsive to PM of diameter 1μm.

Notes:

• Only compatible with Arduino Grove systems
• This sensor uses a counting method to measure dust concentration, not the weighing method, and the unit is pcs/L or pcs/0.01cf
• Please pay attention to the warnings listed here
