Use:

Light detection, brightness detection, the potentiometer can be used to adjust the detection of the brightness valve point, the built-in relay can be used to do various brightness detection switches, you can control a variety of street lights, automatically turn on at night, automatically turn off during the day and control and automation equipment on the car. (Compared with the photoresistor, the directivity is better, it can sense the light source in a fixed direction, detect the light directly in front of the photodiode, the surrounding is difficult to detect, and it should be used for the light search function)

Module Features:

1. The photodiode is used to sense the intensity of light, and the built-in relay controls the load directly.
2. The sensitivity of the power distribution positioner is adjusted. By adjusting the potentiometer, the threshold value of the start relay is set. When it is on, the module relay will be activated. The terminal is to control the switch during the day, and the normally closed and the public terminal is to control the switch at night.
3.Working voltage 5V
4. Output form: directly connected to AC 220V 10A or DC30V 10A load
5, with 4 fixing bolt holes for easy installation
6. Small board PCB size: 5cm x 2.6cm
7, using a wide voltage LM393 comparator

Electrical parameters:

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

Module use instructions:

1. The photodiode is most sensitive to ambient light, and is generally used to detect the brightness of the ambient light.
2. When the module’s ambient light exceeds the set threshold, the relay pulls in, and the public terminal is connected to the normally open terminal. When the ambient light is lower than the set threshold, the relay is opened, and the public terminal is connected to the normally closed terminal;
3. The common terminal is normally open. The normally closed three ports are equivalent to a dual control switch. When the relay coil is energized, the common terminal and the normally open terminal are connected. When there is no power, the common terminal and the normally closed terminal are connected.
