XH-M131 DC 5V 12V 24V 10A Light Control Switch Photoresistor Relay Module Detection Sensor brightness Automatic Control Module

This module can be used as light detection, brightness detection, with a power indicator (red) and relay suction indicator (blue), and with four M3 screw mounting holes, greatly convenient installation, the board can adjust the sensitivity through the potentiometer, comes with a relay, can do a variety of brightness detection control switch, can be used in such as street lights, etc., automatic opening at night, Automatic extinguishing during the day and other equipment requiring automation.

Board parameter

1. The module uses 12V power supply, with anti-reverse connection function, reverse connection power will not damage the module;

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

3. The sensitivity can be adjusted through the potentiometer, and the starting relay threshold can be set by adjusting the potentiometer. When the light is dark at this threshold, the module relay will be disconnected when the light is drawn at this threshold;

Instructions for use

This module can be used as light detection, brightness detection, with a power indicator (red) and relay suction indicator (blue), and with four M3 screw mounting holes, greatly convenient installation, the board can adjust the sensitivity through the potentiometer, comes with a relay, can do a variety of brightness detection control switch, can be used in such as street lights, etc., automatic opening at night, Automatic extinguishing during the day, and other equipment that needs automation

Instructions for use

1. The photoresistor module is more sensitive to ambient light and is generally used to detect changes in the brightness of ambient light;

2. Red light: module work/Blue light: relay work indicator/potentiometer: adjust the detection brightness value (recommended physical test fine-tuning)

3. When the ambient light of the module is dark below the threshold, the relay is drawn, and the common end is connected with the normal opening (disconnected from the normally closed end). When the external light is bright at the set threshold, the relay is disconnected from the common end and the normal opening (disconnected from the normally closed end).

4. The common end is normally open and normally closed, the three ports are equivalent to a double control switch, when the relay coil is powered, the public end is switched on with the normal start, and when there is no power, the public end is switched on with the normally closed end
