ARCELI 12V Light Control Switch Photoresistor Relay Module Detection Sensor XH-M13
ARCELI 12V light control switch photoresistor relay module detection sensor XH-M13
Module with the instructions: In Fig. 1, the photoresistor module is the most sensitive to ambient light and is generally used to control the brightness of the to capture ambient light. 2: When the ambient light is darker than the threshold, the module is set, the relay is energized, the common terminal and normal start are turned on. When the external ambient light is brighter than the set threshold, the relay will turn off the common terminal and the normally closed end are connected; 3, the public side, normally open, normally closed three terminals, the equivalent of a double control switch, the relay coil power, the public end and often the start of the line, the radio, the normally closed line end of the public end; Supply voltage: 12VDC Current: greater than 100mA Load: 250V 10A AC or 30V 10A DC (the current is less than this range can be used) Size: 5.3cm 3cm Quantity: 1pc Package includes: 1pc xDC 12V Photoresistor module relay light detection sensor light switch
Product Features
- The use of the photoresistor induction light intensity is with the relay, the direct control load
- Distribution bit sensitivity setting, start relay threshold set by adjusting the potentiometer, when in the dark this threshold energizes the module relay, light this threshold, the relay enable;
- The 12V power input is for the relay board regulator transistor intended to provide a sensor.
- Onboard optocoupler isolation drive relay, the effective protection of the chip to make the product more reliable;
- Has four fixed screw hole for easy installation
