基于STC12C5401和GSM的环境监测系统设计

Design of Environmental Monitoring System Based on STC12C5401 and GSM

针对传统环境监测系统实时性差的特点,设计开发一种基于GSM模块和单片机技术的无线监测系统,以单片机STC12C5401为微控制器,采用SHT71温湿度传感器对环境温湿度进行采集,同时通过TC35模块以短信的形式将温度数据和湿度数据发送到上位机进行数据分析。系统采用无线传输传送数据,解决了由于环境监测点分布分散,分布范围广而导致监测困难的问题,尤其可以克服环境恶劣引起的环境监测数据传输的不便。采集系统具有电路简单、响应速度快、体积小、功耗低、安装操作方便、测量精度及灵敏度高、抗干扰能力强等优点。

According to the bad real-time property of traditional environmental monitoring system,a wireless monitoring system based on GSM module and single chip technology was designed,with the micro-controller STC12C5401 as control central,the digital temperature and humidity sensor SHT71 was used to collect data of temperature and humidity,and then the data were sent to upper computer by means of SMS.The system solved the difficulties of monitoring caused by the scattered and wide distribution of monitoring sites,and overcame the inconvenience of data transmission resulted from the poor environment.The system had a simple circuit,fast response,small size,low power consumption,easy installation,high accuracy and sensitivity,anti-interference ability.
