Grove - Dust Sensor（PPD42NS） bu_pro each I/O pin can beProvide 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
