5. Oumefar
Light Sensor Switch 12V Stable LDR Photoresistor Relay Module Light Sensor Controller Switch
Oumefar - Photoresistor sensing: this light sensor Switch uses photoresistor to sense intensity of light and good quality relay can directly control load, which can be great helper to you. Effective protection: optical coupling isolation drive relay can effectively protect chip and ensures a better performance, so you don't have to worry about.
Potentiometer adjustment: 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.
Widely application: the light sensor Switch can be widely used for light detection, all kinds of light detection switch, controlling street lamps, brightness detection, and automatic equipment. Stable performance: the photoresistor light Sensor Switch has 12V power supply input special for relay, designed with 78L05 regulated transistor, more stable and reliable.
