基于手机App的植物生长环境监测系统设计

Design of plant growth environment monitoring system based on mobile phone App

针对目前农业种植环境监测系统成本高、布线复杂,监测终端便携性差的问题及多用户远程监测需求,设计了手机作为监测终端且其应用程序(App)监测数据可跨设备远程共享的系统。利用SHT11采集环境温湿度数据,单片机计算露点数据,安卓本地手机通过蓝牙接收数据并通过移动互联网保存数据至网络微数据库,多个安卓远端手机可共享监测数据,并可实现语音、振动以及文字报警。所设计系统成本低、监测终端便携性好,功能可扩性强。经实测,系统运行稳定、精度高,具有广泛的应用前景。

Aiming at the problems of high cost,complex wiring and poor portability of monitoring terminal of present agricultural environment monitoring system and multi-user remote monitoring requirements,a kind of system is designed based on mobile phone as monitoring terminal and its App monitoring data can be shared remotely across devices. The system uses SHT11 sensor to collect environmental temperature and humidity data,through micro-control unit( MCU),dew point data is calculated. Local Android mobile phone can receive data via Bluetooth module and save data to Tiny Web DB via mobile Internet,multiple remote Android phone can share monitoring data from the Tiny Web DB,and can realize voice,vibration and text alarm. The system has the advantages of low cost,good portability of monitoring terminal and strong function expansibility. The test results show that the system runs with high stability,precision and has wide application prospect.
