By using the S3C2440 microprocessor as the core device,using the LTC standard sensor to collect data,using the GPRS module to send and receive data wirelessly,this paper design a wireless monitoring system of greenhouse environment based on GPRS short message. The system has achieved the real-time monitoring of temperature,humidity,illumination and other greenhouse environment data,the data can be sent to cell phone or remote monitoring center in the form of GPRS short message. The microprocessor also has set the standard environmental parameters to send alerts to cell phone when the environment data do not meet environmental requirements. The system also has developed a friendly man-machine interface which is easy to operate.%以S3C2440微处理器为核心器件,用LTC标准传感器采集数据,用GPRS模块无线收发数据,设计了基于GPRS短消息的温室环境无线监测系统.系统实现了对温度、湿度、光照度等温室环境数据的实时监测,测得数据以GPRS短消息的方式发送到手机或远程监控中心;微处理器设置了标准环境参数,当环境数据不符合环境要求时向手机发送警报;系统开发了友好的人机交互界面,操作简便.
