Product features

This module can be used for light detection and brightness detection. It has a power indicator light (red) and a relay pull-in indicator light (blue), and has four M3 screw mounting holes.

The board can adjust the photosensitivity through a potentiometer. It has a built-in relay and can be used as a variety of brightness detection control switches. It can be used in street lights, etc., to automatically turn on at night and turn off during the day, and other equipment that requires automation.

Product parameters

1. The module uses 5V/12V/24V power supply. You can buy it according to your needs. It has anti-reverse connection function. Reverse connection of the power supply will not damage the module.

2. Maximum load capacity of the normally open interface: AC 0V--125V/20A, DC 0V--14V/20A; the module output has three ports common terminal (COM), normally open (CK), and normally closed (CB). The three ports are equivalent to a double-control switch. When the relay coil is powered, the common terminal is connected to the normally open terminal, and when there is no power, the common terminal is connected to the normally closed terminal. The COM terminal is generally connected to the negative pole of the power supply through the load, and the normally open terminal is connected to the positive pole of the power supply.

3. The sensitivity can be adjusted through the potentiometer. By adjusting the potentiometer, the starting relay threshold is set. When the light is dark at this threshold, the module relay is closed. When the light is bright at this threshold, the relay is disconnected.
