The TCRT5000 sensor works in the same way as a general infrared sensor. The TCRT5000 has an infrared transmitting tube and an infrared receiving tube. When the infrared signal of the transmitting tube is received by the receiving tube through reflection, the resistance of the receiving tube changes. Generally, the circuit is reflected in the form of voltage change, and the output result is processed after being converted by ADC conversion or LM324. The change of resistance starts from the intensity of the infrared signal received by the receiving tube, and is often expressed on the reflective surface. The distance between the color and the reflective surface receiving tube is two or two. The hardware reference schematic is as follows:

5-channel tracing module analog output, analog output and distance, object color related. The stronger the infrared reflection (white), the larger the output, the weaker the infrared radiation (black), and the smaller the output. The closer the detector is to the black line, the smaller the output, so that the distance of the black line can be judged by the output analog. The smaller the value, the closer the sensor is to the black line. Compared with other track sensors that can only output high and low levels, the 5-channel analog output of this product can feedback the distance of the black line, and the feedback is more accurate.

5-channel infrared tracking sensor overview:

Based on the TRCT5000 infrared reflection sensor, it is often used to make tracking smart cars. The infrared emitting diode of the TRCT5000 sensor continuously emits infrared rays. When the emitted infrared rays are reflected by the object, they are received by the infrared receiver and output analog values. The output analog value is related to the object distance and the color of the object. The position of the tracking line is judged by calculating the analog value of the five outputs.
