Intelligent Car Robot Diffuse Reflection Obstacle Avoidance Sensor Module

IR Distance Detection Sensor Module | Infrared Obstacle Avoidance | Smart Car Robot Sensor | Adjustable Distance

Product Description:

The IR Distance Detection Sensor Module is designed for smart car robots and automation projects. It features high adaptability to ambient light, making it reliable even in complex environments. The module includes an infrared emitter and receiver. When the emitted infrared light encounters an obstacle (reflective surface), the light is reflected and detected by the receiver. The module processes this signal through a comparator circuit (LM393), turning on the green indicator LED and outputting a digital low-level signal at the OUT pin.

The detection distance is adjustable via the built-in potentiometer, allowing fine-tuning based on your application requirements. It is compact, lightweight, and easy to integrate into Arduino, Raspberry Pi, or other microcontroller-based systems.
