ZIYUN In Grove Dust Sensor,Detection Cigarette Smoke,House Dust Which Are Indoor Asthma Triggers,Detection Air Quality(An Environment Measuring The Dust Concentration)

This Dust Sensor gives a good indication of the air quality in an environment by measuring the dust concentration.
Sensor is to create Digital (Lo Pulse) output to Particulate Matters (PM).
The Particulate Matter level (PM level) in the air is measured by counting the Low Pulse Occupancy time (LPO time) in 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 counting method to measure dust concentration, not weighing method, and the unit is pcs/L or pcs/0.01cf.

Application Ideas:
Air quality sensing
Dustless workshop implementation
Cigarette smoke detection
Air Quality monitoring

Key Features:
Grove compatible interface
Stable and sensitive detection of not only cigarette smoke but house dust which are indoor asthma triggers.
