Module features:
1. Using photodiode to sense the intensity of light, with its own relay, directly control the load
2. With potentiometer to adjust the sensitivity, set the start relay threshold by adjusting the potentiometer. When it is brighter, the module relay pulls in. When it is darker than this threshold, the relay is released, so it is normally open and common. The end is the switch that controls the daytime, and the normally closed and common ends are the switches that control the night.
3. Working voltage 12V
4. Output form: load directly connected to AC 220V 10A or DC30V 10A
5. With 4 fixing bolt holes for easy installation
6. Small board PCB size: 5cm x 2.6cm
7. Use wide voltage LM393 comparator
 
Electrical parameters:
Supply voltage: 12VDC
Current: greater than 100mA
Load: 250V 10A AC or 30V 10A DC
 
Module instructions:
1. Photodiodes are most sensitive to ambient light and are generally used to detect the brightness of ambient light.
2. When the ambient light exceeds the set threshold, the relay is closed, and the common end is connected to the normally open end. When the ambient light is lower than the set threshold, the relay is disconnected, and the common end is connected to the normally closed end;
3. Common end, normally open, normally closed three ports are equivalent to a dual control switch. When the relay coil is energized, the common end is normally connected to the normally open end. When there is no power, the common end and the normally closed end are turned on.

When the ambient light is detected above the set temperature, the relay is closed and the bulb is on. When the temperature is lower than the set value, the relay is turned off and the light is off (the illustration is only the wiring method), which is used for high voltage connection.

When the ambient light is detected above the set temperature, the relay is closed and the bulb is on. When the temperature is lower than the set value, the relay is turned off and the light is off (the illustration is only the wiring method), which is used for the connection of the shared power supply.
