Features:
This module uses photosensitive resistor to sense intensity of light and good quality relay can directly control AC or DC load.

Adjust potentiometer to change sensitivity and set relay start threshold; when it is darker than the threshold, relay is energized; when it is brighter than the threshold, relay is de-energized.
Intelligent control design, after the relay action, it will automatically fine adjust action threshold, which solves the problem of repeated action on threshold.
Module has anti-reverse input function so power reverse input will not cause damage.
Equipped with power indicator light (red) and relay status indicator light (blue).
Designed with four holes for fixing with bolt, convenient to install.

Instruction:
1, Photosensitive resistance module is sensitive to ambient light, commonly used to detect the brightness change of ambient light.
2, Relay module is energized when ambient light is darker than set threshold; COM and NO terminals are connected (disconnect from NC terminal). Relay module is de-energized when ambient light is brighter than set threshold; COM and NO terminals are disconnected (connect to NC terminal).
3, COM, NO and NC terminals are equivalent to a three-way switch. When relay coil is energized, COM is connected to NO terminal. When coil is not energized, COM is connected to NC terminal.

Package Includes:
1 x Photoresistor Relay
