12V light control switch, photoresistor relay module, XH-M131 detection sensor

Using photoresistor light intensity detection with relay, direct load control. Bit-distribution sensitivity adjustment: the relay's start threshold is set by a potentiometer. When the ambient light reaches this threshold, the relay is activated; when it reaches this threshold, it is deactivated. The 12V power input is designed to power the relay board's regulator and provide the sensor with improved stability and reliability. Integrated optocoupler-isolated control relay: effective chip protection for more reliable operation. Four mounting holes facilitate installation. Material: metal. Color: blue. With randomly colored lines. Module operating instructions: 1. The photoresistor module is highly sensitive to ambient light and is generally used to detect its brightness. 2. When the ambient light is below the set threshold, the relay is activated (common terminal + normal start terminal). When the ambient light exceeds the defined threshold, the relay is deactivated (common terminal + normal start terminal). Terminal and normally closed end connected; 3, public side, normally open, normally closed, three ports, equivalent to a double-pole switch, relay coil power supply, public end and often conduction start, radio, public end normally closed conduction; Supply Voltage: 12V DC Current: greater than 100mA Load: 250V 10A AC or 30V 10A DC (current below this range can be used) Size: 5.3cm * 3cm Quantity: 1 piece Package includes: 1 x 12V DC photoresistor relay module, light detection sensor, light control switch Note: Random color, no specified color will be accepted. Note: Light shooting and different displays may cause a slight color difference between the item in the picture and the actual item. The permissible measurement error is +/- 1 to 3 cm.
