Product Description
The infrared reflection sensor detects objects and obstacles using the principle of infrared reflection. An emitter diode emits infrared light, which is reflected by an object. The receiver diode detects the reflected light, and a comparator converts the signal into a digital switching signal.
If there is no object within range, the output provides a high level. If an object is within the set distance, the output switches to LOW and a green LED lights up. A small potentiometer on the circuit board allows the trigger distance to be adjusted to suit the intended application.
The module uses only three connection wires and connects directly to the microcontroller. It is suitable for obstacle detection in moving robots, line following based on light-dark contrasts, counting passing objects, and use as a contactless limit switch.
The permitted supply voltage of 3.3 V to 5 V allows operation with both 5-V and 3.3-V systems without an additional level shifter. The circuit board can be mounted to a chassis or housing using screws.
Safety Information
The module is intended exclusively for building prototypes and for testing and development purposes. It is not suitable for installation in household electrical circuits or safety-critical systems. If you have questions about the power supply, consult a qualified electrician before commissioning.
