Provide reliable data for air purifier system Easy maintenance PWM output Grove compatible interface Compact and light design. This Dust Sensor gives a good 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. Note: This sensor uses a counting method to measure dust concentration, not weighing method, and the unit is pcs/L or pcs/0.01cf. Please pay attention to the warnings listed here. Features: Grove compatible interface(extra wire with connector) Supply voltage range: 5V Minimum detect particle: 1um PWM output Dimensions: 59(W)x45(H)x22(D) [mm] Application Ideas: Air Purifier Air Quality Monitor Air Conditioner Ventilator
