use:
Light detection, brightness detection, potentiometer can adjust the detection brightness valve point, self-contained relay, can do all kinds of brightness detection switch, can control various street lights, automatically turn on at night, automatic extinguishing during the day and on-board supplies control and automation equipment.(Compared with the photoresistor, the directionality is better, the light source in a fixed direction can be sensed, and the light directly in front of the photodiode is detected, and the periphery is difficult to detect, and is often used for the light-seeking function.)
Module features:
1. Using light-sensitive diodes to sense the intensity of light, with its own relay, directly control the load
2. Adjust the sensitivity with the potentiometer. By adjusting the potentiometer, set the threshold of the starting relay. When the threshold is bright, the module relay is closed. When the threshold is dark, the relay is released, so it is normally open and common. The end is the switch that controls the daytime, and the normally closed and common ends are the switches that control the night.
3, working voltage 5V

4. Output form: load directly connected to AC 220V 10A or DC30V 10A
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:
Supply voltage: 5VDC

Current: greater than 100mA
Load: 250V 10A AC or 30V 10A DC
Module instructions:
1. The photodiode is most sensitive to ambient light and is generally used to detect the brightness of the surrounding environment.
2. When the ambient light exceeds the set threshold, the relay is closed, and the common end is connected to the normally open end. When the 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 common end, normally open, normally closed three ports are equivalent to a dual control switch, when the relay coil has electricity, the common end and the normally open end conduct, when there is no electricity, the common end and the normally closed end conduct

Shipping list:
Photodiode with relay module, with photodiode
Module wiring diagram

When the ambient light is detected above the set temperature, the relay is closed and the bulb is on. When the temperature is lower than the set value, the relay is turned off and the light is off (the illustration is only the wiring method), which is used for high voltage connection.

When the ambient light is detected above the set temperature, the relay is closed and the bulb is on. When the temperature is lower than the set value, the relay is turned off and the light is off (the illustration is only the wiring method), which is used for the connection of the shared power supply.
