NDNCZDHC 12V Light Control Switch Detection Sensor Photoresistor Relay Module With Extension Cord
There are 4 fixing bolt holes for easy installation.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 on-board supplies control and automation equipment.
12v Light Switch Moudle:Using the photoresistor to sense the intension of light, with its own relay, directly control the load. Light detection, brightness detection, potentiometer can be adjusted to detect the brightness of the valve point, with its own relay.
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.
12V power input is used exclusively for relays. The onboard 78L05 regulator triode provides sensor comparators to make the product more stable and reliable.
On-board optocoupler isolation drive relay effectively protects the chip and makes the product work more reliably.
