Photoresistor sensor module Photocontrolled switch photosensitive diode Ray receiving brightness detection 3/4 pin 5V

Photoresistor sensor module
Purpose:
Light detection, brightness detection, through the potentiometer can adjust the detection of brightness valve point, with relays, can do a variety of brightness detection switch, can control all kinds of street lights, automatically open at night, automatically extinguished during the day and car supplies control and automation equipment. (Compared with the photosensitive resistance, the direction is better, can perceive the fixed direction of the light source, detect the light in front of the photosensitive diode, it is difficult to detect the surrounding, often should be used in the light search function)
Module Features:
1, the use of photosensitive diode induction light intensity, with relay, directly control the load
2, the distribution potentiometer to adjust the sensitivity, by adjusting the potentiometer, set the starting relay threshold, when the light is in this threshold, the module relay pull, dark in this threshold, the relay release, so the normal open and common end is to control the daytime switch, the normal close and common end is to control the night switch.
