The TCRT5000 sensor works like a conventional infrared sensor, and the TCRT5000 has an infrared emission tube and an infrared receiver tube. When the infrared signal of the launch tube is reflected by the receiving tube, the resistance of the receiving tube changes , In the circuit is generally reflected in the form of voltage changes, and after ADC conversion or LM324 and other circuit shaping after the results of the processing.The resistance changes from the receiving tube to receive the infrared signal strength, often expressed in the reflective surface
