12V Light Control Switch Relay Module Photoresistor Light Detection Switch Sensor

12V Light Control Switch Relay Module Photoresistor Light Detection Switch Sensor

Product Details

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 5 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
