摘　　要：由数字式湿度温度传感器SHT75的原理,设计了一种多功能数字显示温湿度计。该温湿度计具有精密度高、性能稳定、由CRC校验据保证了数据的可靠性;在实时温度和湿度数字显示的同时,能够计算对应露点;且具备电源选择功能。该设计的特点是:USB接口等实现多种数据输出,为温湿度计与其它功能模块结合使用提供了条件,也为温度和湿度的自动控制提供了方便。该温湿度计还能够进一步开发温度和湿度远程自动控制系统。A multi-function digital-display temperature and humidity measuring system is design based on the digital temperature and humidity sensor SHT75. The system has some characteristics of high-precision, stable performances and an ability of CRC data check which can ensure the reliability of data.. The system can display the real-time temperature/humidity , calculate the corresponding point and collect different power supply as required. The feature of this design is that it is possible to output several type data by adopting USB interface ,which provides conditions to combine this part with other modules, and further develops the long-range control system.
