Description:
Light detection, brightness detection, through the potentiometer can adjust the detection of brightness valve points, with relays, can do a variety of brightness detection switches, can control various street lights, automatic opening at night, automatic extinguishing during the day and vehicle supplies control and automation equipment. (Compared with photoresistors, the directivity is better. It can sense the light source in fixed direction and detect the light in front of photodiode. It is difficult to detect the surrounding area, so it should be in the function of searching light).

Feature:
1. Use photodiode to induce light intensity, with relay to control load directly.
2. Distribution potentiometer adjusts sensitivity. By adjusting potentiometer, the threshold of start-up relay is set. When it is light at this threshold, the module relay is sucked in and when it is dark at this threshold, the relay is released. Therefore, the open and public terminals are the switches that control the daytime and the open and public terminals are the switches that control the night.
3. Working Voltage 5V
4. Output Form: Direct Connection with AC 220V 10A or DC30V 10A Load
5. There are four fixed bolt holes for easy installation.
6. PCB Size of Small Plate: 5cm x 2.6cm
7. Using a Wide Voltage LM393 Comparator

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, so it is connected to normally open and common The terminal is to control the switch during the day, and the normally closed and public terminal is to control the switch at night.
3. Working voltage 12V
4. Output form: directly connected to AC 220V 10A or DC30V 10A load
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
