But the rack used to dry clothe is in a low level and has little change so it can not catch up with the rhythm of our life. The residents in modern cities are always busy in their work and can not stay at home during the daytime. When weather goes bad they have no chance to take back their clothes. Based on this problem this paper designs this intellectualized rack used to dry clothes system. This system uses the signal gathered by DS18B20 temperature sensor, CHR01 humidity sensor and 5547 photoresistance sensor to put into the system processing core monolithic integrated circuit AT89S52. Whether to take back the clothes was determined by the current status of temperature, humidity and sunshine. When the relative humidity surpasses the defined value (There is a tendency to rain or have rained) or the sunshine was dark to a special definite value ( The weather turns dark) the system will send out warning and prompt the master to take back the clothes. If there is nobody replying it, the system will send out pulse signal into step motor automotive, control the mechanical part and take back the rack used to dry clothes.
