IR Obstacle Avoidance Sensor Module – Infrared Proximity Detection with Sensitivity Control

🚗 IR Obstacle Avoidance Sensor Module – Infrared Proximity Detection with Sensitivity Control

This IR Obstacle Avoidance Sensor Module is a compact and efficient solution for detecting nearby objects using infrared reflection. It integrates an infrared LED transmitter and a photodiode receiver, allowing it to detect obstacles without physical contact. When an object comes within range, the reflected IR signal is picked up, and the module outputs a digital signal to your microcontroller.

Equipped with an onboard potentiometer, the module allows you to adjust sensitivity (detection distance) to suit your specific needs. It’s an essential component in autonomous robotics, line-following cars, automated doors, and many other Arduino or ESP32-based automation projects.
