Automatic Light Control Curtain Design and Implementation Based on Single Chip Microcomputer
JI Ping;Department of Electronics and Information Engineering,Wentian College of Hohai University;
With improvement of people's quality of life, smart home quickly enters the family, such as automatic light control curtain. In this paper, an automatic light control curtain controlled by two buttons and light sensor is designed with AT89 C52 microcontroller. The light signal collected by the photosensitive resistor PCF8591 is converted into digital signals transmitted to the single chip. After the single chip processing, the signal is transmitted to the motor drive chip ULN2003,which drives the chip drive motor to be turned and reversed. In view of the practical application, manual functions have been added. It can be closed manually, regardless of the intensity of light.
