Feature:
1. Using the photoresistor to sense the intension of light, with its own relay, directly control the load.
2. With potentiometer to adjust the sensitivity, set the starter relay threshold by adjusting the potentiometer. When it is darker than this threshold, the module relay pulls in. When it is bright, the relay is released.
3. 12V power input is used exclusively for relays. The onboard 78L05 regulator triode provides sensor comparators to make the product more stable and reliable.
4. Onboard optocoupler isolation drive relay effectively protects the chip and makes the product work more reliably.
5. There are 4 fixing bolt holes for easy installation.
6. Light detection, brightness detection, potentiometer can be adjusted to detect the brightness of the valve point, with its own relay.
7. Can be used as various brightness detection switches, can control a variety of street lights, automatically open at night, automatic extinguishing during the day and onboard supplies control and automation equipment.
Specification:
Item Type: Light Control Switch Module
Supply Voltage: 12VDC
Current: Greater than 100mA
Load: 250V 10A AC or 30V 10A DC (less than this range of current can be used)
Module Instructions:
1. The photoresistor module is most sensitive to ambient light and is generally used to detect the brightness of ambient light.
2. When the ambient light is darker than the set threshold, the relay is closed, and the common end is connected to the normally open end. When the ambient light is brighter than the set threshold, the relay is disconnected, and the common end is connected to the normally closed end.
3. The common end, normally open, normally closed three ports is equivalent to a dual control switch, when the relay coil is powered, the common end is open to the normally open end, when there is no electricity, the common end and the normally closed end are turned on..
