YWBL-WH 12V Light Sensor Switch,Stable LDR Photoresistor Relay Module Controller Light Sensor, Module

Specification: Voltage: 12VDC Current: >100mA Load Capacity: 250V 10A AC; Or 30V 10A DC PCB 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. Package Includes: 1 × Photoresistor Switch
