This infrared obstacle/object detection sensor is super easy to use. It comes with a potentiometer to adjust the sensitivity. The output is a digital signal so it is easy to interface with any microcontroller such as Maker UNO, Mega, Leornado, Zero, 101, or even the Raspberry Pi or Raspberry Pi Zero. This infrared sensor offers simple, user-friendly, and fast obstacle detection via infrared reflection, it is non-contact detection. As it is based on light reflection, the detection varies with different surfaces. And any infrared source might also interfere with the detection.


It comes in a pair of Infrared emitter and receiver at the front of the module, whenever an object blocks the infrared source, it reflects the infrared and the receiver gets it and the signal goes through a comparator circuit on board. Depending on the threshold that is being adjusted, it will output logic LOW at the output pin and the green LED will light up to indicate the detection. Turning the onboard potentiometer clockwise will increase the sensitivity and further increase the detection range. Compatible with 5V or 3.3V power input.

 

Note: Please make sure that there is a gap between the emitter and the receiver so that the sensor can work properly.
