USES:
Light detection, brightness detection, through the potentiometer adjustable valve testing point, built-in relay, can do all kinds of luminance detection switch, can control all kinds of lamps, automatically open in the evening, automatically go out during the day and the car supplies control and automation equipment.(compared with photosensitive resistance, better direction, can sense the fixed direction of light source, the detection of light, in front of the photodiode's surrounding difficult to detect, often due to light function)

The module features:
1, using photosensitive diode induction light intensity, built-in relay, direct control of the load
2, with a potentiometer sensitivity adjustment, by adjusting the potentiometer, set the start relay valve value, when the light on the threshold, relay and module, dark at the threshold, the relay release, so pick up normally open with the public is the control of the switch during the day, pick up normally closed with the public is to control the switch in the evening.
3, working voltage 12 v
4, output forms: direct connect AC 220 v 10 a or DC30V 10 a load
5, equipped with four fixed bolt hole, convenient installation
6, small board PCB size: 5 cm x 2.6 cm
7, use the LM393 wide voltage comparator

Electrical parameters:
The power supply voltage: 12VDC
Current: 100 ma
Load: 10 a 250 v ac or 10 a 30 v dc

Module USES:
1, the photodiode's most sensitive to ambient light, commonly used to detect the environment around the brightness of the light.
2, module in ambient light more than set threshold, relay, absorption and often start through public end, and when the environment light is lower than the setting threshold, relay disconnect, public end with normally closed end connected;
3, the public side, normally open, normally closed three ports is equivalent to a double switch, relay coil there is electricity, and often start conducting public end, without electricity, public end with normally closed end conduction
