Features The light control switch is controlled by high-quality chips, and the quality is stable and reliable. With a precision adjustable potentiometer to better adjust the sensitivity and delay time. The module comes with a 50cm long photoresistor sensor. The module is equipped with high-power relays, which can control the maximum load current of 10A. The power supply part has diode protection, filter capacitor, anti-interference capacitor and 7805 voltage regulator chip, which can provide stable voltage and prevent the module from being burned due to the reverse connection of the power supply.

Wiring: First connect the corresponding DC power supply to DC+ and DC-; 2. Plug in the sensor probe and power on (Ensure that the voltage meets the requirements, the polarity cannot be reversed); 3. Delay Adjustment: The time range when plug in the jumper S2 is 1-20 seconds, otherwise the time range is 1-200 seconds. Adjusting the delay potentiometer clockwise will extend delay time. When adjusting the sensitivity, you must adjust the delay time to the shortest delay time of about 1 second (counterclockwise adjust for about 10 circles);   Package List
