use:
Light detection, brightness detection, through the potentiometer can adjust the detection brightness valve point, with a relay, can be used as a variety of brightness detection switches, can control various street lights, automatically turn on at night, automatically extinguished during the day, and on-board supplies control and automation equipment. (Compared with the photoresistor, it has better directivity, can sense the light source in a fixed direction, and detect the light directly in front of the photodiode. It is difficult to detect the surrounding area, and it is often used for the light-seeking function)
Module features:
1. The light-sensitive diode is used to sense the intensity of the light, with a relay to directly control the load
2. The sensitivity of the power distribution positioner is adjusted. By adjusting the potentiometer, the threshold of the starting relay is set. When it is brighter than this threshold, the module relay is closed, and when it is darker than this threshold, the relay is released. The end is to control the switch during the day, and the normally closed and public end is to control the switch at night.
3. Working voltage 12V
4. Output form: directly connected to the load of AC 220V 10A or DC30V 10A
5. There are 4 fixing bolt holes for easy installation
6. Small board PCB size: 5.6cm x 3.4cm
7. Use wide voltage LM393 comparator
Electrical parameters:
Power supply voltage: 12VDC
Current: more than 100mA
Load: 250V 10A AC or 30V 10A DC
Module instructions:
1. Photodiodes are the most sensitive to ambient light, and are generally used to detect the brightness of the ambient light.
2. When the module’s ambient light exceeds the set threshold, the relay is closed, and the common terminal is connected to the normally open terminal. When the ambient light is lower than the set threshold, the relay is turned off and the common terminal is connected to the normally closed terminal;
3. The common terminal, normally open and normally closed three ports are equivalent to a double 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.
