LDR sensor module is a low-cost digital sensor as well as analog sensor module, which is capable to measure and detect light intensity. 

Application:
Light detection, brightness detection, the brightness valve point can be adjusted through the potentiometer, and it comes with a relay, which can be used for various brightness detection switches.
Module features:
1. The photoresistor is used to sense the intensity of the light, and it comes with a relay to directly control the load
2. The sensitivity of the potentiometer is adjusted, and the starting relay threshold is set by adjusting the potentiometer, when the threshold is on, the module relay is engaged, and when the threshold is dark, the relay is disconnected.
3. Working voltage: 5VDC, 12VDC
4. Output form: directly connected to AC 220V 10A or DC30V 10A load
5. It is equipped with 4 fixing bolt holes, which is convenient for installation
6. Small board PCB size: 5cm x 2.6cm
7. Use a wide voltage LM393 comparator

Instructions for using the module:

1. The photoresistor module is sensitive to ambient light and is generally used to detect the brightness of the light in the surrounding environment.
2. When the ambient light of the module exceeds the set threshold, the relay is engaged, and the common end and the normally open end are connected, and when the external ambient light is lower than the set threshold, the relay is disconnected, and the common end is connected to the normally closed end;
3. The three ports of common end, normally open and normally closed are equivalent to a double control switch, when the relay coil is electrified, the common end and the normally open end are on, and when there is no electricity, the common end and the normally closed end are on;

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