5 Pieces Photoresistor Relay Module, 12V DC Light Control Switch with Adjustable Sensitivity, Optocoupler Isolation for DIY Electronics Projects

This photoresistor relay module uses a light-sensitive sensor to detect ambient light intensity and control connected loads via an onboard relay. The sensitivity threshold is adjustable with a potentiometer: when the light level drops below the set point, the relay energizes; when it rises above, the relay releases.<br><br>Key Features:<br>- 12V DC power input with voltage regulator for stable operation<br>- Onboard optocoupler isolation drives the relay, protecting the chip for reliable performance<br>- Four mounting holes for easy installation<br>- Adjustable sensitivity via potentiometer<br>- Relay contact rating: 250V 10A AC or 30V 10A DC (load should be within this range)<br>- Current consumption: approx. 100mA<br>- Module dimensions: 5.3cm x 3cm<br>- Material: metal, blue PCB<br>- Comes with connecting wires (color random)<br><br>How to Use:<br>1. Connect 12V DC power to the module.<br>2. Turn the potentiometer to set the light threshold.<br>3. Connect your load to the common (C), normally open (NO), and normally closed (NC) terminals. When the relay is energized, C and NO are connected; when de-energized, C and NC are connected.<br><br>Package Includes:<br>5 x 12V Photoresistor Relay Module Light Control Switch<br><br>Note: Wire color is random and cannot be specified. Due to lighting and display variations, actual color may slightly differ. Measurement tolerance: ±1-3cm.
