In this paper, the design of temperature controls platform based on MSP430F149 is introduced. It also introduced the software and hardware design of this system .In this design, a precision integration circuit transducerTEMP101 is adopted to measure the temperature in real time, and the signal measured is inputted into the MSP430F149 directly. The setting temperature can be inputted into the system through the keyboard. The setting temperature and the temperature of current can be displayed on the LCD. The design of this product is aimed at producing a small power consumption, low operating voltage, with the norms of the Line of Control and data lines, to facilitate the interface with other application controllers.
