12V Stable LDR Photoresistor Light Sensor LDR Relay Switch Relay Module Controler Light Sensor Switch

Features:

• This switch uses photoresistor to sense intensity of light and good quality relay can directly control load.
• Adjust potentiometer to change sensitivity and set relay start threshold; when it is darker than the threshold, relay is energized; when it is brighter than the threshold, relay is de-energized.
• 12V power supply input special for relay, designed with 78L05 regulated transistor, more stable and reliable.
• Optical coupling isolation drive relay can effectively protect chip and ensures a better performance.
• Widely used for light detection, brightness detection, all kinds of light detection switch, controlling street lamps, and automatic equipment.

Specification:Voltage: 12VDCCurrent: >100mALoad Capacity: 250V 10A AC; Or 30V 10A DCPCB Size: 5*2.6cm/1.96*1.02"Instruction:1, Photosensitive resistance module is sensitive to ambient light, commonly used to detect the brightness change of ambient light.2, Relay module is energized when ambient light is darker than set threshold; COM and NO terminals are connected. Relay module is de-energized when ambient light is brighter than set threshold; COM connect to NC terminal.

3, COM, NO and NC terminals are equivalent to a three-way switch. When relay coil is energized, COM is connected to NO terminal. When coil is not energized, COM is connected to NC terminal.
