PPD4NS and PPD20V Dust Sensors by Shinyei

The PPD4NS and PPD20V dust sensors available from Shinyei are capable of detecting dust in homes. When installed in products, the sensors automatically control air-purifiers and monitor air quality.

PPD60PV, a newly developed sensor, is designed to detect particles cleanliness class 100,000 ~ 1,000,000. The sensor can be installed in clean systems and fan filter units to control cleanliness of operation line.
