Seeed Studio 101020012 - Grove - Dust Sensor (PPD42NS)
This Dust Sensor gives a good indication of the air quality in an environment by measuring the dust concentration.
Wide measurement range: Not only cigarette smoke, but also indoor dust, an asthma trigger, can be detected.
Stable and sensitive measurements: dual PWM output for particle sizes over 1 micron and 2.5 microns (approx.)
Long-term use: Air is self-priming through the current of the air generating mechanism with built-in heater, easy to maintain
Compact and light design, easy to install
Easy to use: compatible with Grove port, just plug-and-play
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 the weighing method, and the unit is pcs/L or pcs/0.01cf.
