  • Function of the light-sensing power supply module

    Function of the light-sensing power supply module

    A photocell is a small, low-power, and easy-to-use light-sensitive module. It is a sensor that changes the resistance of an electrical circuit based on the amount of light present in the surroundings. Thus, it helps control smart lights and other devices automatically. A Light Sensor generates an output signal indicating the intensity of light by measuring the radiant energy that exists in a very narrow range of frequencies basically called “light”, and which ranges in frequency from “Infra-red” to “Visible” up to “Ultraviolet” light spectrum. These devices convert light energy into electrical signals and are widely used in areas such as solar panels, cameras, security sensors, and.
