Introduction
This IR proximity sensor senses objects in light or dark conditions. The sensor can automatically detect objects in front of the sensor as far as the set distance. This distance can be adjusted anywhere from 0.4 to 157 inches. (1-400cm)
In addition, the sensor features digital signal output, which works well with Arduino IO expansion board and relays. It can be widely used in applications like smart home, house security, intelligent detection and control, robot obstacle, and so on.
The sensor is based on the principle of diffuse reflection of laser on the object. When a person or object enters the sensing range in front of the sensor, the sensor immediately determines that there is induction, so as to control the output signal; after the person or object leaves the sensing range, it will judge that there is no induction, and stop signal output, by which intelligent control can be achieved.

How to adjust detection distance
Keep the sensor powered on and in the normal operating status. Place a piece of paper (or other objects) in front of the sensor at your desired sensing distance. The distance adjustment steps are as shown in the diagram, enter the distance adjustment mode: hold on the adjustment button, when the red LED indicator flashes, enter the automatic distance adjustment mode; don’t move the sensor and paper when the LED flashes, when the LED indicator stops flashing, the distance adjustment is done.
