The estimated delivery time offered by Amazon is not the real time. Your patience is highly appreciated. Hope you will receive your item soon and enjoy using it.
Light detection, brightness detection, test and adjust brightness threshold via potentiometer, comes with relays, can do all kinds of brightness detection switch.
Can control various street lights. They can automatically be opened at night while automaticlly shuts off in the daylight and control the car gadget and automatic equipment.Adopts photosensitive resistance to sense the strength of light, together use with relay, can directly control the load
Euipped with potentiometer to adjust the sensitivity. Set and start the relay threshold value by adjusting the potentiometer. When the strength of light is lower than this threshold value, relay module will attract to close while it is higher than the threshold, the relay module will break off

Specifications :

Working voltage: DC 12V
Working current: > 100mA
Output forms: AC 250V 10A or DC30V 10A ( can be used within the range of lower than 10A current )
12V power is specially used for the relay. Onboard 78L05 regulator transistors is used for sensor and comparator, to make the product more stable and reliable;
Onboard opto-isolator driven relay, can effectively protect the chip, to make sure the product more reliable work.
With four mounting bolts holes for easy installation
Adopts wide voltage LM393 comparator
Instruction:
1 Photosensitive resistance sensor module is very sensitive to light of environmental. It is generally used to detect the brightness of ambient light.
2 When the brightness of ambient light is lower than the set threshold value, the relay attracts to close and the common port and normal open port will be connected; while the brightness of the ambient light exceeds than the set threshold value, the relay breaks off and the common port and normal close port will be connected.
3 The common port, normal open and normal close port are equivalent to a double control switch. When there is electricity in the relay coil, the common port and normal open port are connected while there is no electricity in the relay coil, the common port and normal close port are connected.

Package Includes :

*1 x Photosensitive Sensor Module
1 x Extension Cable
