Dust Sensor
Application:
Air purifierProduct characteristics:
Good consistencyDescription
TX940-D07 is a universal and miniaturized laser dust sensor module. Using the principle of Mi scattering, it can detect the dust particles in the air, and it has good consistency and stability through professional algorithm and calibration detection process. The sensor has the ability to output serial port and PWM simultaneously, which makes it easy to use. Small size, easy to integrate applications.
