Abstract: Combined with automatic control theory, sensor technology and semiconductor refrigeration technology, the design and realization of the temperature automatic control system based on MSP430F149 MCU is introduced. This system consists of the processing core module which based on MSP430F149 MCU, the sensor detection module, the semiconductor driver module, the semiconductor refrigeration module and the LCD display module. Moreover, in order to adjust the temperature in the box equal to the setting value, the PID algorithm is utilized to perform the dynamic adjust for the temperature. After the startup of the system, the temperature value can be set by keyboard, and the sensor can get the temperature value in the box and send the data to the processing core module. And then, a novel multi-parameter PID algorithm is utilized to control the performance of the semiconductor driver module. With the effect of the semiconductor driver module, the temperature in the box can finally be adjusted by the semiconductor refrigeration module according to the setting value. In addition, the work condition of the semiconductor refrigeration module can be displayed by the light, furthermore, the realtime shown of the temperature change can also be perform by the LCD display to improve the capability of the human computer interaction.
