About this item

The IR Infrared Obstacle Avoidance Sensor Module is a compact module designed for detecting obstacles in robotics applications. It operates within a voltage range of 3.6V to 5V and utilizes an LM393 comparator chip for processing signals. The sensor has a detection distance ranging from 2 to 30 cm and a detection angle of 35°, making it suitable for close-range obstacle detection. The module features a 3-wire interface (Vcc, GND, and OUTPUT), with the output providing a low-level signal when an obstacle is detected. It also includes a green indicator LED that lights up when an obstacle is present. The sensor is easy to assemble and use, with 3mm screw holes for convenient mounting. Its compact size and low power consumption make it ideal for integration into various robotics projects, including line-following robots and automated systems requiring obstacle detection. The module's affordability and reliability make it a popular choice among hobbyists and professionals working with microcontrollers like Arduino
