This module is a three-way switch (COM, NO and NC) that uses the intensity of the ambient light to directly control the output load. Its adjustment potentiometer allows you to change the sensitivity and set the threshold for starting the relay. The relay is energized when it is darker than the threshold.
The optical isolation relay effectively protects the chip and ensures better performance.
This module is used for light detection, brightness detection , control of lamps and automatic equipment. Characteristic: - Channels: 1
