This module is 12V power supply stable version, without delay function, the relay is no light pull, light off
Light detection, brightness detection, by detecting the brightness potentiometer adjustable valve points relay comes, 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.
1, the light intensity of the photosensitive resistance sensing, comes relay, direct load control
2, distribution position sensitivity adjustment by adjusting potentiometer to set the threshold to start the relay, when this dark threshold module relay, light when this threshold, the relay release;
3,12V power input relays designed for use onboard 78L05 regulator transistor, providing a sensor Used comparison, make the product more stable and reliable;
4, on-board relay driver optocoupler isolation, the effective protection of the chip, to make products more reliable work;
5 with 4 fixing bolt holes for easy installation
6, small PCB board size: 5cm x 2.6cm
7, using a wide voltage comparator LM393
1, ambient light module photoresistor most sensitive, generally used to detect the brightness of ambient light.
2, in dark ambient light module in the set threshold, the relay, common and normally open ON ,, when ambient light is brighter than the set threshold value, the relay is switched off, the common and normally closed terminal is turned on;
3, common, normally open, normally closed three ports is equivalent to a dual-control switch, relay coil when there is electricity, common and normally open conduction, without electricity, the common terminal and the normally closed end conduction;
Supply voltage: 12VDC
Current: More than 100mA
Load: 250V 10A AC or DC 30V 10A (lower than current within this range can be used)
