The light sensor module adaptable to the environment , having a pair of infrared transmitter and receiver, launch tube a certain frequency, infrared , when the obstacle detection direction ( reflection surface ) , the infrared receiver is reflected back by the receiver tube , after processing through the comparator circuit , the green indicator light will illuminate while the signal output interface output digital signal ( a low-level signal ) can be adjusted via potentiometer knob detection distance , the effective distance range 2 ~ 80cm, working voltage is 3.3V- 5V. The detection range of the sensor can be adjusted via potentiometer , with little interference , easy to assemble , easy to use , can be widely used in robot obstacle avoidance , obstacle avoidance trolley line counts , and black and white line tracking , and many other occasions .
