FC-51 INFRARED OBSTACLE SENSOR MODULE IR TO ARDUINO

Module Description

The ambient light adaptive sensor module, which has a pair of infrared emitting and receiving tubes, the transmitting tubes emit a certain infrared frequency, when the direction of an obstacle (reflective surface) is detected, the reflected infrared is received by the tube receiving, after a processing comparator circuit, the green light is on, but the digital signal interface output signal (a low-level signal), you can adjust the detection distance knob potentiometer, the range Effective distance of 2 ~ 30 cm, operating voltage of 3.3V - 5V. The detection range of the sensor can be obtained by adjusting the potentiometer, with little interference, easy to assemble, user-friendly functions, can be widely used in robot obstacle avoidance, car avoidance, line counting and line tracking in black and white and many other occasions.
