Design of Temperature Remote Control System Based On Single Chip Microcomputer

This paper introduces a temperature remote control system based on single chip microcomputer and VB.Ditital temperature sensor is adopted in this system,through simple and pratical output control circuit,two storehouse temperature is automatic monitor,and with the error of measurement less than ±0.625℃.using RS-232 serial bus,user can remote control temperature.functions such as alarm temperature set-up,display,draw,storage,query,statistic and control is realized.This system has high automatic degree,good human-computer interaction and easy to extend.economy and practicality is good.The system was tested and the test result showed that this system could achieve quite good control performance.
