Instructions for use：
1、When powered on, the power indicator light is always on；
2、When the distance is far away and no obstacle is detected, the output indicator light is off, and the OUT pin outputs a high level
3、When the distance is short, when an obstacle is detected, the output indicator light is on, and the OUT port outputs a low level
4、When the distance is short, when encountering a black obstacle, the black lamp cannot receive it, the output indicator is off, and the OUT pin outputs a high level
5、The transmitting tube (white lamp) emits infrared rays of a certain frequency. When the detection direction encounters an obstacle (reflecting surface), the infrared rays are reflected back and accepted by the receiving tube (black lamp). After being processed by the comparator circuit, the output indicator light will be Lights up, and outputs a digital signal (low level signal) at the same time.
