12V power supply stable version witH 50cm long lead photosensitive resistance sensor module
Use:
Detect light, brightness detection. Through the potentiometer can adjust the brightness detection valve point, comes with a relay, do a variety of brightness detection switch, can control all kinds of street lamps, starts automatically in the night, daytime automatically etinguished and the vehicle activities control and automation equipment.
Module features:
1, the use of photosensitive resistance of the intensity of the light, with the relay, direct control of the load
2, with potentiometer sensitivity adjustment, by adjusting the potentiometer, set the starting relay threshold, when the brighter than this threshold, module and relay, dark in this threshold value, the relay is released. Therefore, connected with a normally open and the common end is to control the switch during the day and connected with a normally closed and the common end is to control the switch of the night.
3, using the 12V power input eclusively for relay, onboard 78l05 regulator triode, provide sensor comparator, make the product more stable and reliable;
4, output form: directly connected to the 220V 10A AC or 10A DC30V load
5, small size: 6cm 1.9cm PCB
6, using a wide voltage LM393 comparator
Electrical parameters:
Supply voltage: 12VDC current: more than 100mA
Load: 10A 250V AC or 10A 30V DC

Delivery list:
1 way 12V light sensor and relay module 1,50cm long lead wire with a photosensitive resistance.
