Abstract:

With the continuous innovation of science and technology and the arrival of the information age, daily life intelligence is everywhere and intelligent product development and change has brought people unlimited convenience. Temperature real-time monitoring system is one of the most representative examples. How to study and develop a real-time temperature monitoring system of good performance, achieve accurate temperature measurement and control is the main content of this subject. Nowadays, national electronic technology is steadily improving and designing real-time temperature monitoring system with microcontroller as the core and temperature sensor as the key measurement and control components has become the current mainstream design.

Paper’s main contents are as follows: the real-time temperature monitoring system background, the significance of the research and the development of this field at home and abroad. Review the relevant theoretical knowledge of the MSP430G2553 microcontroller, temperature sensor DS18B20, Nokia5110 LCD display and MH-FMD speaker and the use of the required software design. After accomplishing the preliminary preparation of the project, the system program is going to be designed, programmed and debugged and the circuit schematic of the real-time temperature monitoring system will be drawn and the fabrication of the printed circuit board will be completed. After completing this series of work, a simple temperature real-time monitoring system will be presented in front of everyone.
