Description
A compact reflective photoelectric sensor designed for Arduino, ESP32, Raspberry Pi, and smart robot car projects — that is the IR Infrared Obstacle Avoidance Sensor Module. The module uses an infrared transmitting LED and an infrared receiving photodiode to detect nearby obstacles by sensing reflected IR light. When an object enters the detection range, the onboard LM393 comparator processes the reflected signal and outputs a digital LOW signal through the OUT pin. A built-in indicator LED lights up at the same time, making it easy to see when an obstacle has been detected. The detection distance can be adjusted using the onboard potentiometer, allowing you to set the sensing range from approximat
