摘要
利用蓝牙无线传输的便利性和互联网传输数据的灵活性,采用安卓手机作为数据汇集与上传中心,使用n RF51822作为数据采集终端控制与蓝牙传输中心,DHT11作为温湿度采集模块,同时利用手机采集图片和GPS信息。安卓手机通过蓝牙连接n RF51822芯片,接收到环境数据后将其打包,通过互联网发送到远程服务器端,可将结果通过微信公众号或网页在客户端上进行分析与展示。数据采集终端采用蓝牙4.0低功耗芯片n RF51822,使用两节5号电池即可工作半年以上。此设计满足了环境采集传感器的实用性和可移动性。
The use of Bluetooth wireless transmission convenience and the flexibility of the Internet transmission of data,the use of Android mobile phone as a data collection and upload center,the use of n RF51822 as a data acquisition terminal control and Bluetooth transmission center,DHT11 as a temperature and humidity acquisition module,while using mobile phones to collect pictures and GPS information. Android mobile phone through the Bluetooth connection n RF51822 chip,after receiving the environmental data will be packaged,sent to the remote server through the Internet,the results can be displayed by We Chat public or web page on the client for analysis and display. Data acquisition terminal using Bluetooth 4.0 low-power chip n RF51822,the use of two batteries on the 5 th can work more than six months. This design meets the practicality and mobility of the environmental acquisition sensor.
