【Warm Tips】： To figure out your values for the Sensitivity , Please set the delay time to its minimum value first , this will save your time. 【Motion Activated】 : Sensor function triggered by motion, you can use this small motion sensor switch to control lighting like Led strip lighting. 【Delay Time Adjustable】: The delay time controls how long the light stays on once it gets triggered, during the delay time if motion detected, the delay time will reset and start a new delay time. 【Sensitivity Adjustable】: The sensitivity controls how close you need to be to the sensor in order to activate it.

This product has a variety of unique self-test functions, automatic temperature compensation, anti high frequency interference and other functions, the experiment proves that the detector can work reliably under the high frequency interference of 20~1000mhz (such as mobile). The circuit design adopts the pulse counting technology. P.COUNT selects the jump pin J1 for the pulse count, and selects to insert the first-stage pulse count for the general indoor environment. The selected one is the secondary pulse count for the harsh environment. The factory setting is one-stage pulse count. The working voltage: DC 9-16V, mount method: wall Mounted, installation height: about 2.2m, detection distance: 32 feets(10m), detection angle: 110°, alarm output: NC/NO optional, the factory setting is NC, working temperature: -10°C~+50°C(14℉~122℉). This product has the alarm output normally closed / normally open optional function, in order to facilitate the connection of different alarm host, the user can adjust the RELAY jump pin J2 on the PCB as needed. Select to insert N.C. (normally closed state), select to unplug N.O. (normally open state), the factory setting is N.C. (normally closed state).
