The IR Obstacle Avoidance module is perfect for Arduino projects. They work as serial modules, meaning you only need a single pin from your Arduino to control a sensor. Now you can add as many IR sensors to your Arduino project as your Arduino has I/O pins! This is the perfect module for robot cars and other devices that require a low-cost distance sensor.
This module includes both an Infrared (IR) light out and an IR sensor to pick up the reflection of the light in a specific direction. This makes it easy to build robot that has many sensors at different positions, each requiring only a single pin from your Arduino or other Microcontroller.

IR Obstacle Avoidance Sensor Module Tutorial: Reflective IR Detection, Threshold Tuning, and Arduino Code
This tutorial is a comprehensive, practical guide to the IR Infrared Obstacle Avoidance Sensor Module (Leobot Product #266). You will learn how the module detects nearby objects using reflected IR light, how the onboard <strong>LM393 comparator</strong> produces a clean digital output, how to tune the sensitivity for a stable detection window, and how to integrate one or many sensors into Arduino-based robot cars and obstacle detection systems.
