The design is to reduce costs, expand the development of the scope and the system running stability, reliability, designed by MSP430F149 monolithic integrated circuits to control the temperature sensor and figures DS18B20 plete the temperature of the collection, the temperature in the number of ways in led display LED1602, achieve the temperature of the collection and display and police. The minimum temperature values based on actual requirements, the keyboard for set, for automatic temperature control and other function, and the hardware and software system of the programming process the design of hardware to constitute a part of six modules, power and resets the collected, keyboard, the module display module and. MSP430F149 isa 16-bit flash chips including the type of operation ofa monolithic integrated circuits, the development of device easy, but the characteristics and programming for the control system design a great convenience., all modules ofa schematic diagram ofa circuit are protel plete.
