<div><p>Package includes:1pc XH-M131 Photosensitive relay module Output method: 1 way relay Model:XH-M131 Voltage:5V/12V Name:Photosensitive relay module Size:53*31*19mm This module can be used for light detection and brightness detection. It has a power indicator (red) and a relay pull-in indicator (blue), and has four M3 screw mounting holes, which greatly facilitates installation. The board can be adjusted by a potentiometer. Photosensitive sensitivity, built-in relay, can be used as a variety of brightness detection control switches, can be used in street lights, etc., automatically turn on at night, automatically turn off during the day, and other equipment that requires automation. Parameters: 1. The module adopts 12V power supply and has anti-reverse connection function. Reverse connection power will not damage the module; 2. Maximum load capacity of normally open interface: AC 0V--125V / 20A, DC 0V--14V / 20A; the output of the module has three ports: common terminal (COM), normally open (CK), normally closed (CB), three Each port is equivalent to a dual control switch. When the relay coil is energized, the common terminal is connected to the normally open terminal. When there is no power, the common terminal is connected to the normally closed terminal. The COM terminal is generally connected to the negative pole of the power supply through the load, and the normally open end is connected to the positive pole of the power supply. ; 3. The sensitivity can be adjusted through the potentiometer. The threshold value of the start relay can be set by adjusting the potentiometer. When the light is darker than this threshold, the module relay is activated. When it is brighter than this threshold, the relay is turned off.</p></div>
