This design takes the 16-bit ultra-low power MSP430F149 micro controller produced by TI Company as the control core. Using a high-precision single-bus device DS18B20 as the temperature sensor, the keyboard as the temperature input setting, and the temperature value displayed by the 1602 LCD, temperature measurement and controlling are realized within the closed environment. And the nRF401 wireless transmission module could transfer the temperature value to the PC. Through the PID algorithm, the system has a high temperature measuring and control accuracy. The system circuit has a simple, clear structure, easy to use and save energy. What is more, it is convenient to be directly remote monitored through PC.
