LDR Photoresistor Relay Module, Controler Light Sensor Switch Photosensitive Resistance Module 12V

Product Description

✔ This switch uses photoresistor to sense intensity of light and good quality relay can directly control load.

✔ 12V power supply input special for relay, designed with 78L05 regulated transistor, more stable and reliable.

✔ 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.

✔ 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
