SPECIFICATIONS

This product is a module composed of single-channel and dual-channel line tracking sensors. It is compatible with various single-chip microcomputer control boards, such as ARDUINO series single-chip microcomputers. Its connection port is compatible with ARDUINO sensor expansion boards. The working principle of the TCRT5000 infrared pair tube on the sensor is to utilize the different reflectivity of infrared rays to colors and convert the strength of the reflected signal into a current signal. The sensor is effective at high level when detecting black, and at low level when detecting white. The detection height is 0–3CM. In the circuit, you can use a knob potentiometer to adjust the sensitivity of black and white tracking.
