【Abstract】 This paper presents a new design of hardware and software based on MSP 430 micro-controller for the temperature and humidity testing system.The MSP 430 F 149 micro-controller is used as the central unit and an integrated temperature and humidity sensor AD 590 and HM 1500 is applied.The system possess of many excellences,including its novel structure,simple circuit and expedient control.The upper and lower limit value of the temperature and humidity detected by this system can be set discretionarily and an alarm will be given by system if the temperature exceeds the limits.Experimental proof of the system’s low cost,high reliability and have high practical value.更多还原
