Products from the USA may come with an input voltage of 110V–120V, requiring a step-down transformer. Check the device wattage to select the correct power converter.
•Using photosensitive sensor to sense the intensity of light, with a relay, direct control of the load.
•With the potentiometer to adjust the sensitivity, by adjusting the potentiometer, set the start relay threshold, when the sensor senses the light brightness is greater than this threshold, the module relay pull, when the sensor senses the light brightness is less than this threshold, the relay release , The relay switch is disconnected.
