介绍了一种无线温湿度实时监测系统。系统以低功耗单片机 MSP430F149为主控制器，选用高精度低功耗温湿度传感器 SHT21测量环境的温湿度，并采用高精度实时时钟芯片 PCF8563为系统提供时间基准。系统根据实际需要设置温湿度的阈值，当所在环境的温湿度超出该阈值时，系统会发生报警，并将当前所处环境的时间、温湿度值和相关提示信息通过 GPRS 传输到移动终端。系统实现了对环境温湿度的无线实时监测，可适用于多种环境中。

A wireless and real-time system which can monitor temperature and humidity is introduced.This system takes MSP430F149 as the low-power microcontroller,and employs SHT21 which is a high precision and low-power temperature and humidity sensor to measure the temperature and humidity.Mean while,PCF85 63 which is a high accuracy real time clock chip is applyed to provide the system's time benchmark.This system sets the thresholds of temperature and humidity based on the actual demand,and it will give an alarm and send the local time,the value of temperature and humidity,and the relevant prompts indicates to the mobile terminal by GPRS when the value of temperature or humidity is out of the range.The system is for the wireless and real-time monitoring temperature and humidity,and could be employed in multiple environments.
