IR Infrared Obstacle Avoidance Sensor Module for Arduino & ESP32

The Infrared Obstacle Avoidance Module is a simple, Arduino-ready proximity sensor that helps your robot detect nearby objects and avoid collisions. It actively emits infrared light and reads the reflection to spot obstacles in front of a rover, smart car, or walking robot, making it a great “eyes up front” add-on for autonomous builds. A built-in potentiometer lets you adjust the detection distance (typically around 2 cm to 30 cm), and it outputs a straightforward digital signal when something is detected, so your code stays clean and fast with no analog conversion needed. With a convenient mounting hole, it’s easy to install on common 2WD/4WD chassis, and its quick response makes it useful for bots that need immediate stops or turns. It can also be used for short-range triggers in simple indoor automation projects like touchless dispensers or small DIY activators.
