12V Light Control Switch Relay Module Photoresistor Light Detection Switch Sensor

Features:

Using photosensitive resistance induction light intensity， built-in relay， direct load control.
With a potentiometer sensitivity adjustment， by adjusting the potentiometer， set the start relay valve， when the threshold is darker， relay module closing， when the threshold is brighter， the relay release.
12V power input， onboard 78L05 regulator transistor， make the product more stable and reliable.
on-board optical coupling isolation drive relay， the effective protection of the chip， to make products more reliable work.
With 4 fixing bolt holes for easy installation

Specification:

Using a wide voltage comparator LM393
PCB size: 5cm x 2.6cm
Supply voltage: 12VDC
Current: More than 100mA
Load: 250V 10A AC or DC 30V 10A (lower than this range current can be used)

Module Description:

Photosensitive resistance module is the most sensitive to ambient light， generally used to detect the brightness of ambient light.
Common， normally open， normally closed three ports is equivalent to a dual-control switch， when the relay coil is electricity， common and normally open conduction， when without electricity， the common terminal and the normally closed conduction;

Usage:

Light detection， brightness detection， through the potentiometer can adjustable valve testing point， comes with relay， can do all kinds of brightness detection switch， you can control all kinds of lights， turn on automatically at night， during the day and automatically turn off， car supplies control and automation equipment.

Package includes:

1 x Light Control Relay Module
