In this paper, we design a temperature control system, improve the comprehensive 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 microcomputer intelligent temperature control system, with MSP430 single chip microcomputer as the core, adopting the temperature sensor DS18B20, based on the GPRS wireless communication module, based on the AT commands and data collector, to build a remote temperature data acquisition system, to control the temperature.
