Module function introduction:
The infrared transmission diode of the TCRT5000 sensor is constantly launching infrared rays. When the emitted infrared rays are not reflected or reflected, but the strength is not large enough, the optical triode is always in a state.It has been extinguishing; when the detected object appears within the detection range, the infrared rays are reflected and the strength is large enough. The light -sensitive triode is saturated. At this time, the output end of the module is high, indicating that the diode is lit.

Circuit diagram

AO is a different voltage when the sensor receives different reflex distances. It is an analog signal, and the DO is the digital signal output
