LDR Photoresistor Relay Module 12V

This module is designed to detect the brightness of ambient light using a photoresistor. It activates a relay when the light level falls below a set threshold, making it ideal for various automation projects.

Specifications

• Net Weight: 16g
• Working Voltage:  12V
• Load Power: AC 250V/10A, DC 30V/10A
• Mounting: Bolt hole for easy installation

Instructions

1. The photoresistor module is most sensitive to ambient light and is generally used to detect the brightness of the surrounding environment.
2. When the ambient light is darker than the set threshold value, the relay is energized, causing the common terminal and the normally open terminal to connect. When the external ambient light is brighter than the set threshold value, the relay is de-energized, causing the common terminal and the normally closed terminal to connect.
3. The module includes three ports: common side, normally open, and normally closed. These function as a dual-control switch. When the relay coil is powered, the common end and the normally open terminal conduct. Otherwise, the common end and the normally closed terminal conduct.
