Obstacle Avoidance Sensor

The Obstacle Avoidance Sensor is an infrared (IR) based distance detection sensor designed to help robots and smart systems detect nearby objects without physical contact.

Using an IR emitter and receiver pair, the module detects reflected infrared light from obstacles in front of it. When an object is detected within range, the digital output signal changes state making it extremely easy to interface with microcontrollers.

With an adjustable detection distance and fast response time, this module is ideal for robotics, automation systems, and beginner-friendly Arduino projects.

Compact, affordable, and reliable a must have for every robotics kit.
