In this paper, we design a temperature control system, improve the prehensive use of temperature detection system single chip as micro controller, digital temperature sensor, the temperature control, puts forward a remote temperature monitoring system scheme based on GPRS technology, the scene is realized by using MSP430 MCU and DS18B20 digital temperature sensor temperature data acquisition and processing, again by MG323 GPRS module to achieve remote data transmission and receiving, has features of high precision and good stability. A hardware design based on single chip microputer intelligent temperature control system, with MSP430 single chip microputer as the core, adopting the temperature sensor DS18B20, based on the GPRS wireless munication module, based on the AT mands and data collector, to build a remote temperature data acquisition system, to control the temperature. Keywords Temperature acquisition system。 DS18B20。 Single chip microputer。 GPRS。 目 錄 IV 目 錄 摘 要 ...........................................................................................................................
