Operating Voltage and Current Rating: the supply voltage of PIR controller is 12 V to 24 V, and the electric current is 6 A; confirm the relevant parameters use to safetyAdjustable Detention Period: the sensing distance of the PIR motion sensor is about 5 m/ 16.4 ft to 8 m/ 26.25 ft, and there is a time setting button at the back of the controller, which can be rotated to set the delay minutes of turning off the switch from 1 to 10 minutesOperating Principle: the working principle of the PIR sensor, whose sensor sensing angle of is 120, that the load switch is controlled by the infrared detecting mode, is simple, and you can install the sensor in the proper environment according to your actual needsEasy to Install and Use: connect the load cables first and then the power cables, to that there is no short circuit between the cables of the infrared motion light switch powering on the device, and then set the delay time; When a person is detected, the load light is turned on, and when the person is for a set number of minutes, the load light automatically goes off and Lightweight: the waterproof infrared motion detector made of quality plastic measures . 11.99 x 5.99 x 5.99 cm, and the right size makes it easy to use or the detector at some you with saving spaceMaterial:plasticcolour:blackPackage Contents:3 * PIR sensorsOnly the above package content, other are not included.Note: Light and different displays may cause the color of the item in the a little different from the real . The measurement allowed is +/- 1-3cm.
