Description
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 1m.
Note
This sensor uses a counting method to measure dust concentration, not the weighing method, and the unit is pcs/L or pcs/ 0.01 cf.
Please pay attention to the warnings listed here.
