INTRODUCTION

Photoresistor or light-dependent resistor (LDR) or photocell is a light-controlled variable resistor. The resistance of a photoresistor decreases with increasing incident light intensity; in other words, it exhibits photoconductivity. A photoresistor can be applied in light-sensitive detector circuits, and light- and dark-activated switching circuits. A photoresistor is made of a high resistance semiconductor. In the dark, a photoresistor can have a resistance as high as several (MΩ), while in the light, a photoresistor can have a resistance as low as a few hundred ohms. If incident light on a photoresistor exceeds a certain frequency, photons absorbed by the semiconductor give bound electrons enough energy to jump into the conduction band. 
The resulting free electrons conduct electricity, thereby lowering resistance. The resistance range and sensitivity of a photoresistor can substantially differ among dissimilar devices. Moreover, unique photoresistors may react substantially differently to photons within certain wavelength bands.


FEATURES
Stable version of the module is 12V supply, without delay function, pull relay matt, bright disconnect
using the photoresistor induction light intensity comes with the relay, direct control load,Distribution bit sensitivity adjustment, start relay threshold set by adjusting potentiometer,when the dark this threshold,  module relay is energized, bright this threshold, the relay release;
12 V power input is designed for relay board  regulator transistor to provide sensor Used to make the product more stable and reliable;
on board optocoupler isolation drive relay, the effective protection of the chip to make the product more reliable work;
has four fixed bolt hole for easy installation
small board PCB size: 5cm x 2.6cm
