Jopto 12V Light Control Switch Photoresistor Relay Module Detection Sensor XH-M131 Brightness Automatic Control Module Light Control Relay Light Switch

• The photoresistor relay module can be used for light detection and brightness detection.
• The module uses 12V power supply and has the function of anti-reverse connection. Reverse connection of the power supply will not damage the module.
• Adjust the sensitivity of the light through the potentiometer, with a relay, can be used as a variety of brightness detection control switch.
• With four M3 screw mounting holes, it greatly facilitates installation.
• It can be used in, for example, street lights, which are automatically turned on at night, automatically turned off during the day, and other equipment that requires automation.

Feature: The module can be used for light detection and brightness detection. With power indicator (red) and relay indicator (blue). With four M3 screw mounting holes, it greatly facilitates installation. The module can adjust the sensitivity of the light through the potentiometer, with a relay, can be used as a variety of brightness detection control switch. It can be used in, for example, street lights, which are automatically turned on at night, automatically turned off during the day, and other equipment that requires automation. The module uses 12V power supply and has the function of anti-reverse connection. Reverse connection of the power supply will not damage the module. Specification: Normally open interface load capacity: AC 0V-125V/20A, DC 0V--14V/20A; The output of the module has three ports: common (COM), normally open (CK), and normally closed (CB). The three ports are equivalent to a dual-control switch. When the relay coil is energized, the common end and the normally open end are connected. When electricity, 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. Material: metal Color: blue Size: 53 × 30 × 19 mm Wire length:approx. 35 cm Weight: 19.7 g Package Content: 1 × Photoresistor Module Relay
