2-Channel IR Reflective Sensor

Description

Set consisting of two TCRT5000 reflection sensors and a small management board based on the LM393 chip. When one of the sensors approaches a light-colored object, the intensity of the received signal increases and the LED on the management board turns red (digital output high). When a dark-colored object approaches, the intensity decreases and the LED turns off (digital output low). The management board has status LEDs (digital outputs and power), trimmers to adjust the detection distance, and digital outputs. Suitable for line detection, for example to help a robot follow a black line on a white background or vice versa.
