TCRT5000 photoelectric sensor module is based on the TCRT5000 infrared photoelectric sensor design of an infrared reflective photoelectric switch. The sensor is composed of a high transmitting power infrared photodiode and a high sensitivity phototransistor, the output signal is shaped by a Schmitt circuit and is stable for examination.The TCRT5000 sensor works with a general infrared sensor application a transmission and a sensing.The TCRT5000 has an infrared transmitting tube and an infrared receiving tubeWhen the infrared signal from the transmitting tube is received by the receiving tube through reflection, the receiving tube's The resistance will change, in the circuit is generally reflected in the form of voltage changes, and after the ADC conversion or LM324 and other circuit shaping until the output results of the processing, the change in resistance from the strength of the infrared signal received by the receiving tube, often expressed in the reflective surface colour and reflective surface of the receiving tube distance two and aspects.
