1.Sensing principle: non-contact infrared sensor, designed with MCU circuit produced in using the principle of diffuse reflection of infrared light on objects. When a person or object enters the sensing area set by the sensor, the sensor outputs a signal, and the sensor turns off the output after the person or object leaves the sensing area.
2.Adjustable sensing distance: 10cm-100cm adjustable, clockwise adjustment distance is far, counterclockwise adjustment distance is close, the knob cannot rotate 360°.
3.Application: widely used in faucet sensing, bank self-service terminals, advertising light boxes, advertising machines, Face recognition machine, toilet flushing, automatic hair dryer, automatic doorbell, automatic door, TV close-range TV watching reminder, etc.
