Title Environment detection system design of temperature and humidity sensor based on SMTH08I                                                      

Abstract With the wide application of temperature and humidity monitoring system, detection of temperature and humidity by different industries and areas have different requirements and standards. The temperature humidity detection system through using United States Texas instrument company production of 16 bit super low power MSP430F149 single tablets machine and digital type temperature humidity sensor SMTH08I completed, text in the analysis has temperature humidity measurement of work principle and the process, made temperature humidity detection system design of overall programme, completed has system of power circuit, and sensor circuit, and controller circuit, communications circuit, module circuit principle of design. Software designed to complete the planning and design of the inpidual modules of the program modules and program realization for temperature and humidity signal processing programming and debugging. Final adoption of the systems software hardware online testing, completed the design of temperature and humidity signal detection.
