Design of temperature control system based on MSP430 and LabVIEW

Zhang Shuai

Abstract

This paper designs a temperature control system,which uses mix signal process MSP430F149 and digital thermometer DS18B20 as hardware design core,LabVIEW 8.5 as software designing platform.By MSP430 collects the digital information from DS18B20,the LabVIEW analyzes and processes the sampling signals in software platform to achieve real time temperature control.Simultaneously,the acquired data is saved for analysis and check at any time.The system measurement accuracy is 0.062 5 ℃.Because of low power's system feature,real time monitoring circumference temperature in internal power supply long time.
