• DIY Projects: Integrate into automated mechanisms or smart devices requiring surface detection.

How It Works

The module uses infrared LEDs and phototransistors to detect the reflectivity of surfaces. When placed above a surface, black surfaces absorb IR light while white or reflective surfaces reflect IR light back to the sensors. Each channel provides a digital HIGH or LOW output depending on the detection, which can be read directly by microcontrollers.

The onboard potentiometer allows users to adjust the detection threshold, improving accuracy under different lighting conditions or surface types. With real-time response, the 4-channel module ensures smooth and precise navigation for robots and vehicles.

Example Project

A typical application is a 4-wheel line-following robot. Each IR sensor channel monitors the track beneath the robot. The microcontroller receives digital signals and adjusts the motor speeds to keep the robot aligned with the line.

Another application is a maze-solving robot, where the IR tracking module helps detect edges and follow the correct path. It can also be used for edge detection on conveyor belts in DIY automation projects.
