Grayscale sensor: a shining pearl in the development of science and technology

Grayscale sensor, an electronic component that measures light intensity and converts it into digital signals, is widely used in various fields. It calculates the grayscale level of light by comparing the brightness of the received light with the preset standard value. Grayscale sensor is mainly composed of photosensitive elements, filters, amplifier circuits, interface circuits, etc. Its working principle is based on the photoelectric effect. The reflection of light is sensed by the photosensitive element and the current signal is converted into a digital signal.
