This sensor is mainly used for cultivation in agriculture, forestry, greenhouses and other fields, as well as for measuring natural and artificial light. The working principle of a light sensor is to convert light intensity values ​​into voltage values, that is, by sensing the intensity of light and converting it into an electrical signal. This sensor is usually composed of a photosensitive element and a signal processing circuit. The photosensitive element can sense light and generate an electrical signal proportional to the intensity of light, and the signal processing circuit amplifies, filters and digitizes this electrical signal for subsequent measurement and analysis.
