This design uses the MSP430F149 microprocessor as the core processor, DS18B20 temperature sensor collected temperature information acquisition and processing, and real-time display and control. Via the keyboard to set the alarm temperature, higher or lower than the alarm temperature, the system alarm. This article focuses on the hardware and software programming of the system design process. The hardware has six parts: the power and reset module, the temperature acquisition module, the keyboard input module, display module and alarm module. Up the test environment, the system functional tests and indicators for testing, test results show that the test results is consistent with the actual ambient temperature and the temperature alarm is also more sensitive in addition to
