Photosensitive resistance sensor plus 5v relay module light sensing light control switch no light detection

Purpose:
Light detection, brightness detection, adjustable brightness valve point through potentiometer, built-in relay, can be used as various brightness detection switches.
Module features:
1. Using photoresistors to sense the intensity of light, with built-in relays to directly control the load
2. Adjust the sensitivity with a potentiometer. By adjusting the potentiometer, set the threshold for starting the relay. When it is above this threshold, the module relay will engage, and when it is below this threshold, the relay will disconnect.
3. Working voltage 5VDC, 12VDC
4. Output form: directly connected to AC 220V 10A or DC30V 10A load
5. There are 4 fixed bolt holes for easy installation
6. Small PCB size: 5cm x 2.6cm
7. Using a wide voltage LM393 comparator

Module usage instructions:

1. The photoresistor module is sensitive to ambient light and is generally used to detect the brightness of surrounding light.
2. When the ambient light exceeds the set threshold, the relay is closed and the common terminal and normally open terminal are connected. When the ambient light is below the set threshold, the relay is disconnected and the common terminal and normally closed terminal are connected;
3. The common terminal, normally open, and normally closed ports are equivalent to a dual control switch. When the relay coil is powered, the common terminal is connected to the normally open terminal, and when there is no power, the common terminal is connected to the normally closed terminal;

Electrical parameters:
Power supply voltage: 5VDC, 12VDC
Current: greater than 100mA
Load: 250V 10A AC or 30V 10A DC
