环境温湿度检测系统设计

Design of environment temperature and humidity detecting system

设计一款数字式温湿度检测仪,可用于日常环境中的温、湿度的测量与记录。系统以MSP430F2232为核心,利用单片全校准数字式相对温、湿度传感器SHT15检测温/湿度,利用电擦写式只读存储器24LC512作为存储元件。系统可完成温、湿度的测量和记录,同时还可以记录对应的日期与时间,并通过液晶屏显示温、湿度数据及其变化曲线。利用VC语言开发的温、湿度数据接收软件还可以把数据传送到PC机,便于对这些数据进行分析和对比。系统预留有扩展口,以便于更新和升级。

Design a digital temperature and humidity tester, which can be used for measuring and recording the daily environment temperature and humidity. The system takes MSP430F2232 as the core, uses monolithic full calibration digital temperature and relative humidity sensor SHT15 to detect temperature and humidity, and uses electrically erasable read-only memory 24LC512 as the storage element. The system can measure and record temperature and humidity, and can also record the corresponding date and time. The temperature, humidity and the variation curve can be displayed on the LCD. The software developed with VC language for receiving temperature and humidity can send the data to PC machine for analysis and contrast. The system also has set aside a expansion port, easy to update and upgrade.
