The product has small size, low power consumption, wide measurement range, short response time, and convenient and fast application

This dust sensor product utilizes the principle of optical illumination to measure the dust concentration within the detection range through the conversion of optical path and circuit. It can sensitively detect dust particles with a diameter of over 1MM and directly apply a microcontroller for UART communication. The product has small size, high accuracy, low power consumption, wide measurement range, short response time, and convenient and fast application.
