    Abstract

    In order to display the luxmeter of illumination and the induced voltage of illuminance, we design illuminometer based on a single chip microcomputer simulation, and the photoelectric conversion circuit, amplifier filtering circuit, A/D conversion circuit, display circuit and alarm circuit. The hardware circuit system is built. The debugging is completed. Experiments show that the system of illuminometer can display the induced voltage effectively.
