Abstract
In this paper the low-power temperature measurement system is designed by using AT89S52 microcontroller and configuring multiple temperature sensors.The system consists of temperature measurement unit,storage unit,display unit and other accessories.The temperature data having been gathered is displayed on LCD and can be commnunicated through a serial port RS232 to PC.By using Proteus,the simulation is realized by combining the host computer(PC) with the lower computer(microcontroller).The LabVIEW program on PC will finish receiving data from MCU and displaying them.
