Package
Contains
1x photo resistor relay module
Product Description
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 78L05
regulator transistor to provide sensor Used to make the product more stable and
reliable;
4, onboard opt coupler 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
7, wide voltage LM393 comparator
Module using the instructions:
1, photoresistors module is most sensitive to ambient light,
generally used to detect the brightness of the ambient light.
2, the module when the ambient light is darker than the
threshold value is set, the relay is energized, the common terminal and the
normally start is turned on, when external ambient light is brighter than the
set threshold value, the relay is switched off, the common terminal and the
normally closed end connected;
3, the public side, normally open, normally closed three
ports, the equivalent of a dual-control switch, relay coil power, public end
and often the beginning of conduction, radio, public end normally closed
terminal conduction;
Electrical parameters:
Supply voltage: 12VDC
Current:> 100mA
Load: 250V 10A AC or 30V 10A DC (the current is less than
this range can be used)
Shipping list:
Light the 12V-sensitive resistor sensor plus a relay module
1, weld the photoresistor with 50CM long lead, a jumper cap
