This obstacle sensor module works with LM393. It has a pair of infrared transmitting and receiving sensors. The infrared LED emits IR signals a certain frequency and when an obstacle appears on the line of infrared light, it is reflected back by the obstacle which is sensed by the photodiode (which works as an infrared sensor).
The detection sensitivity and distance can be adjusted with the potentiometer on the module. The distance range is 2-30cm which means that the sensor module can detect obstacles or object that are within the range of 2-30cm.
Moving the potentiometer in clockwise direction increases the detection distance and moving in the counter-clockwise direction decreases the detection distance.
NOTE: This module is suitable for educational purpose only, not suitable for industrial use and not suitable for end user products. If you use it for any industrial use and if it fails, we are not responsible for it. We won't replace or make refunds for used parts.
