Sell XH-M131 5V 12V Light Control Switch Photoresistor Relay Module Detection Sensor 10A brightness Automatic Control Module For Arduino best price

Input: DC 5V / 12V Load capacity: 10A / AC 250V or DC up to 30V RED LED ON: Indicate the Power ON BLUE LED ON: Relay is working Module output terminal has three ports Normally open ( NO ) Common terminal ( COM ) Normally closed ( NC ) Size: 53*31*19mm Light threshold can be adjusted by potentiometer to set the relay start Relay-Sensor Light detection, brightness detection, the detection brightness valve point can be adjusted through the potentiometer, with a relay, can be used as a variety of brightness detection switches, can control various street lights, automatically turn on at night, automatically extinguish during the day, and control and automation equipment for on-board supplies. Module features: 1. Using photoresistor to sense the intensity of light, with a relay to directly control the load 2. The sensitivity of the power distribution positioner is adjusted. The threshold of the starting relay is set by adjusting the potentiometer. When it is darker than this threshold, the module relay is closed, and when it is brighter than this threshold, the relay is disconnected. 3. Working voltage 5V 12V 4. Output form: directly connected to the load of AC 220V 10A or DC30V 10A 5. There are 4 fixing bolt holes for easy installation 6. Small board PCB size: 5cm x 2.6cm 7. Use wide voltage LM393 comparator Module instructions: 1. The photoresistor module is sensitive to ambient light and is generally used to detect the brightness of the ambient light. 2. When the module's ambient light exceeds the set threshold, the relay is closed, and the common terminal is connected to the normally open terminal. When the ambient light is lower than the set threshold, the relay is turned off and the common terminal is connected to the normally closed terminal; 3. The common terminal, normally open and normally closed three ports are equivalent to a dual-control switch. When the relay coil is energized, the common terminal and the normally open terminal are connected; when there is no power, the common terminal and the normally closed terminal are connected; Electrical parameters: Power supply voltage: 5V 12VDC Current: more than 100mA Load: 250V 10A AC or 30V 10A DC
