IR Sensor Module Infrared Obstacle Avoidance Sensor for Arduino and Robotics Projects

This IR sensor detects objects in front of it using infrared light. It sends out an infrared beam and checks if it bounces back, then gives a simple HIGH or LOW signal to your Arduino or other board. Connect three wires, upload a short sketch, and your project can sense obstacles.

Where You Can Use an IR Sensor

It is a favourite module for beginner robotics. You can build an obstacle-avoiding robot, a line follower, an automatic tap, an object counter or a simple touchless switch. The board has an onboard LED that lights up when something is detected, and a small knob to adjust the detection range. It works with Arduino, Raspberry Pi, and other microcontrollers.

Product Highlights

• Infrared obstacle detection module with transmitter and receiver
• Simple 3-pin connection: VCC, GND, and OUT
• Onboard LED shows when an object is detected
• Adjustable detection range with a small knob
• Good for line followers, robots, and object counters
