The sensor module is adaptable to ambient light, having a pair of infrared emitting and receiving LEDs, transmitting LED emit infrared certain frequency, when the direction of an obstacle is detected, the infrared reflected is received by the reception LED, After a comparator circuit processing, the obstacle light is on, but the signal output interface output digital signal (a low-level signal), you can adjust the detection distance trim potentiometer, the effective distance range of 2 ~ 20cm, the working voltage of 3.3V- 5V. The detection range of the sensor can be obtained by adjusting the potentiometer, with little interference, easy to assemble, easy to use features, can be widely used in robot obstacle avoidance, avoidance car, line count, black and white line tracking, and many other applications.
