Original stock TCRT5000 reflective photoelectric switch photoelectric sensor TCRT5000L tracking car special

Product Descriptions：

The working principle of TCRT5000 sensor is the same as that of general infrared sensors, with one transmission and one sensing TCRT5000 has an infrared emitter tube and an infrared receiver tube When the infrared signal of the transmitting tube is reflected and received by the receiving tube, the resistance of the receiving tube will change, which is generally reflected in the form of voltage changes in the circuit. After ADC conversion or LM324 circuit shaping, the processed output result is obtained The change in resistance is determined by the intensity of the infrared signal received by the receiving tube, which is often reflected in two aspects: the color of the reflective surface and the distance between the reflective surface and the receiving tube The hardware reference schematic is as follows:
