Package parameters:

Working voltage: 5V DC voltage (5V relay is generated)

Tips: (welding 5v relay, working voltage is 5V; Welding 12v relay, working voltage is 12V)

Load: 250V 10A AC or 30v 10a DC (the current below this range can be used);

Board size: 3.0 * 7.0cm

Features:

The module can be used for light detection and brightness detection. It can adjust the threshold of brightness detection by potentiometer, and has its own relay. It can be used as various brightness detection switches, and can control various street lamps, automatic equipment, etc. It is automatically turned on when there is no light at night, and automatically turned off when there is light in the daytime; Or it is automatically turned on when there is light in the daytime, and automatically turned off when there is no light at night.

Benefits:

1. With the delay function, the delay is 3 to 5 seconds. When the brightness is in the critical state, the relay will not operate and reset in frequency;

2. Optional working mode: Relay action when there is light or relay start when there is no light can be selected

When the switch is pressed, the relay starts when there is light;

When the switch pops up, the relay starts when there is no light;

3. Sensitivity can be adjusted, adjusted by potentiometer, clockwise, increasing sensitivity;

4. The product adopts high-quality relay, which can bear 1500W load and meet the requirements of most people;

5. The product has power supply indicating red light and relay suction indicating green light;

Problem debugging:

The switch pops up (it detects that when there is no light at night, the equipment is started, and it is not started when there is light at dawn): when there is no light at night or when there is no light at night, the relay does not attract or start, please rotate the potentiometer anticlockwise to the appropriate value to attract and start; When it is bright or bright, the relay will continue to attract and start. Please adjust the potentiometer clockwise to the appropriate value. The relay will not start when it is released.

Press the switch (start the device when detecting that there is light on the day, and do not start when there is no light at night): when there is light on the day, the relay does not attract or start, please rotate the potentiometer clockwise to the appropriate value and start it; When it is dark or dim, the relay will continue to start it. Please rotate the potentiometer counterclockwise to the appropriate value and the relay will not start when it is released.

Note: The potentiometer has a total stroke of 28 laps. If there is no response, adjust it for a few more laps. If it is adjusted to the end, it will sound KAKA, just adjust it backwards
