Abstract: In today's era of rapid development of science and technology，microcontroller technology , an important part of information technology，is an unprecedented development .Temperature in modern industrial control, monitoring of the agricultural production, ecological environment and people's daily life also gradually become an important test parameters ，and the temperature measurement also become a hot research topic .

This paper proposes a remote wireless temperature measurement based on MSP430F149 MCU ，begins with the learning of background and significance of the topic, determining design after referencing data, determining devices after analyzing and comparing, and design the system hardware and software. In the end，make up the system as a whole after the functional test and put forward the improvement scheme.

System mainly include the temperature acquisition module, GPRS communication module, GPS module and main control module. Master device uses 16-bit MCU MSP430F149 series famous for its high performance low power consumption, temperature acquisition module select DS18B20 as the main device, GPRS module uses SIM900A as the main chip, it implements the data upload rapidly and accurate. PC by accessing web access to relevant data. After test, this system can operate stably. And has high credibility, simple circuit structure and anti-interference ability. It can achieveing the demand of practical and feasible.

Keywords: MSP430F149 MCU、DS18B20 temperature sensor、GPS positioning、GPRS communication
