Product Details

Use:

2 road light detection, detection and brightness and 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. Also can do two sensors, two conditions trigger output end in series (gate), any of the conditions of the two kinds of trigger, the output end in parallel (or gate), two groups of independent control of 3 kinds of control way of directly connected to the AC power.
Module features:
1, the use of photosensitive resistance sensor, the intensity of the light, comes 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 4.3cm PCB
6, using a wide voltage LM393 comparator
Electrical parameters:
Power supply voltage: 12VDC
Current: more than 200mA
Load: 10A 250V AC or 10A 30V DC
Module instruction:
1, photosensitive resistance module is the most sensitive to environmental light, generally used to detect the brightness of the surrounding environment of light.
2, module in the light more than setting a threshold, a relay, a public end and often start connected, and when the outside ambient light is less than a preset threshold, the relay to disconnect, the public end with the normally closed terminal is connected.
3, the public side, normally open, normally closed three ports is equivalent to a double control switch, relay coil power, the public and often start conducting, without electricity, the public and the normally closed end;
