Description
The Infrared (IR) sensor is a highly versatile proximity module that emits and detects infrared light to identify nearby obstacles or contrasting colours. It is a cornerstone component in educational STEM kits for teaching the principles of light reflection, environmental sensing, and basic autonomous navigation. Typically featuring an onboard potentiometer for manual range calibration, it provides a straightforward digital output that interfaces seamlessly with microcontrollers such as the Arduino UNO and Magic Board. This sensor is fundamental for students building line-following robotic cars, maze-solving algorithms, and close-range edge detection systems.
