XH-M131 light detection sensor relay module for 12V systems

Product Description Utilizes a photoresistor to sense light intensity, directly controlling the load via a relay. Sensitivity adjustment is provided; the relay activation threshold is set by adjusting the potentiometer. When the light is dim and reaches this threshold, the module relay is energized; when the light is bright and reaches this threshold, the relay is de-energized. A 12V power input is designed for the relay board's voltage regulator transistor, providing voltage to the sensor and making the product more stable and reliable. Onboard optocoupler isolation drives the relay, effectively protecting the chip and making the product more reliable. Four mounting bolt holes are provided for easy installation. Material: Metal Color: Blue Includes wiring, wire color is random. Module Usage Instructions: 1. The photoresistor module is most sensitive to ambient light and is typically used to detect ambient light brightness. 2. When the ambient light is dimmer than the set threshold, the module relay is energized, and the common terminal is connected to the normally open terminal; when the ambient light is brighter than the set threshold, the relay is de-energized, and the common terminal is connected to the normally closed terminal. 3. The common side has three ports: normally open and normally closed, equivalent to a double-control switch. After the relay coil is energized, the common terminal is connected to the normally open terminal; after radio wave conduction, the common terminal is connected to the normally closed terminal. Power Supply Voltage: 12VDC Current: 100mA Load: 250V 10A AC or 30V 10A DC (current less than this range can also be used) Dimensions: 5.3cm x 3cm Quantity: 5 pieces Package List: 5 x 12V DC photoresistor module relays, light detection sensors, and light control switches Note: Cable colors are random; specified colors are not accepted. This package only includes the above contents and does not include other products. Note: Light reflection and different monitors may cause the color of the item in the picture to differ slightly from the actual item. The measurement tolerance is +/- 1-3cm.
