A photosensitive resistor is a resistor resistance made by semiconductor photoelectric effect value and the incident light intensity change; incident light intensity, resistance decreases, the incident light is weak, increase of resistance. Photosensitive resistors are generally used for control survey, of the light and photoelectric conversion (the light changes into electrical changes). Light water lamp through a photosensitive device (resistance), automatic switch. For many production and life, such as in the workshop installation control switch to control the lights in the workshop, it is conducive to the workshop lighting and help conserve electricity, light bright enough when the switch will automatically turn off the lights. Application of optical light water in daily life has been fully in the market began to promote. This pape summarizes the basic principles and characteristics of photosensitive resistance, and introduces the basic structure of photosensitive resistance and circuits for implementing control functions; and introduces its design scheme for control the lamp, and commissioning and performance analysis of program.
