DC 12V Photoresistor Relay Module Light Brightness Timer Detection Controller Switch On Off with Wires Compatible with Automotive Applications

• Model supports DC 12V input voltage, making it compatible with standard automotive electrical systems and common low-voltage power supplies.
• Designed for light-sensitive automatic control, the photoresistor detects ambient brightness changes to trigger relay switching for lights, fans, or other 12V loads.
• Includes adjustable sensitivity and delay time dials, allowing fine-tuning of activation thresholds and on/off timing for varied conditions.
• Comes with pre-attached wires and screw terminals for straightforward installation in cars, RVs, boats, or outdoor enclosures without requiring soldering.
• Functions as both a dusk-to-dawn switch and timer-based controller, supporting applications such as automatic interior , security , or -saving illumination circuits.
