Data Acquisition and Analysis of Photocell Characteristics and Its Application in Switch Circuit Control

Abstract

Photocells which produce a voltage and supply an electric current when illuminated have been widely used. The basic characteristics of the photocell were tested and analysed through experiments by an optical control experimental platform, such as short circuit current, open circuit voltage, illumination characteristic, volt ampere characteristic, load characteristic, and spectral characteristic. The experimental results are in agreement with the theoretical analysis. The light control switch circuit was realized by using photocell. In this way, the principles and operation of photocell can be well comprehended.
