The Infrared Tracking Sensor Module is an infrared detection module designed for smart cars, line-following robots, and DIY electronics applications. The module integrates an infrared transmitter and receiver. When the emitted infrared light meets a reflective surface, the reflected signal is received and processed by the onboard circuit. The module can output a digital signal through the S pin, and it also provides an analog signal output through the A pin.
