12V light control switch the photoresistor plus relay module the light detection switch photosensitive sensor

Product Description:

Stable version of the module is 12V supply, without delay function, pull relay matt, bright disconnect
 
Uses:
Light detection and brightness detection, detection can be adjusted via potentiometer brightness valve point comes relays, and do all kinds of brightness detection switch, you can control all kinds of street lights automatically turn on at night, during the day and automatically turns off and car supplies control and automation equipment.
Module Features:
1, 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, the module relay is energized, bright this threshold, the relay release;
3,12 V power input is designed for relay board  regulator transistor to provide sensor Used to make the product more stable and reliable;
4, onboard optocoupler isolation drive relay, the effective protection of the chip to make the product more reliable work;
5, has four fixed bolt hole for easy installation
6 small board PCB size: 5cm x 2.6cm
