Application note of Sharp dust sensor GP2Y1010AU0F

(string dust, etc.) should not enter the inside of the sensor. The installation of a coarse mesh filter in front of dust through hole is effective for the capture of big dust . ・Please consider the maintenance by vacuum cleaner in preparation for the false sensor output by the attachment of dust to the inside of the sensor.

Grove - Dust Sensor

Grove - Dust Sensor Introduction . 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 given time unit. LPO time is proportional to PM concentration.
