LDR Photoresistor Relay Module 12V

The LDR Photoresistor Relay Module 12V is engineered to gauge the intensity of ambient light via a photoresistor. The relay is triggered when the light intensity dips below a predetermined level, making it a perfect fit for a range of automation tasks.

Specifications

• Net Weight: 16g

• Mounting: Bolt hole for convenient mounting

Instructions

The photoresistor module exhibits maximum sensitivity to ambient light, and is typically employed to measure the brightness of the surrounding environment.When the ambient light becomes dimmer than the preset threshold value, the relay is activated, leading to a connection between the common terminal and the normally open terminal. Conversely, when the external ambient light is brighter than the preset threshold value, the relay is deactivated, resulting in a connection between the common terminal and the normally closed terminal.The module is equipped with three ports: common side, normally open, and normally closed. These serve as a dual-control switch. When the relay coil is energized, the common end and the normally open terminal are conductive. In the absence of power, the common end and the normally closed terminal are conductive.
