摘　　要：设计并实现了一种基于MSP430F123单片机温湿度控制系统,主要包括了控制器的硬件和软件设计.系统利用单线数字温度传感器DS18B20和湿敏电阻进行温湿度测量,在分析了温度及湿度的测量原理、噪声影响和计算方法基础上进行补偿,设计系统软件,通过温湿度测量来控制测量区域的加热器和加湿器的工作,最终确保仪器箱在合适的外界环境下稳定工作.本系统设计的温湿度控制器已小批量生产,用在各种仪器控制箱中.经测试表明,该系统简单,操作方便,成本低.测量范围:-40～85℃,RH20%～95%.Temperature and humidity control system based on MSP430 is designed and realized in this paper, including software and hardware design of this controller. Temperature and humidity are measured using one-wire digital thermometer DS18B20 and humidity-sensitive resistance. Based on analyses of measuring principle of temperature and humidity, influence of interference and algorithm, system software is designed. The heat and humidity in measuring field are controlled by measured temperature and humidity, finally verifying the steady working of measuring meter in the meter box. The temperature and humidity controller in this system have been produced in small batch and used in various meter controller box. Testing proved that this system is simple, operating- convenient and low-cost. Measuring range： -40℃～85℃ ,20% ～ 95%RH.
