Compact Optical Dust Sensors

Avaiability: In stock


optical dust sensor has an internal infrared diode and a phototransistor diagonally arranged. The diode projects light and the phototransistor detects the dark spots caused by the fine particles passing through. In addition to this feature, depending on the pulse pattern outputted you can check whether or not is smoke or dust.

This is the sensor you will need if you want to measure air particles, build an air purifier system, or detect certain particles. Includes a special cable to connect with other aplications.

Project 1: Environmental Monitoring System Based on OBLOQ-IoT Module
This product is mainly applied in electronic laboratory to monitor and control indicators such as temperature, humidity, light and dust, and timely upload them to the cloud data space to achieve remote monitoring and control of dehumidifier, air purifier, exhaust fan and dimmable light, etc. in the laboratory.
