摘　　要：针对现有温湿度监测系统存在成本和能耗偏高等问题,设计一款低能耗的温湿度记录系统。该系统基于近场通信(NearFieldCommunication,NFC)和温湿度传感等技术,硬件部分主要由温湿度传感器模块、NFC标签模块、实时时钟(Real Time Clock,RTC)模块以及主控制芯片组成。各模块由锂电池供电,系统提供有效的充电管理,主控制芯片通过输入输出(Input Output,IO)口输出电流给NFC标签等模块供电,以降低能耗。同时,为了方便查阅温湿度记录,设计基于NFC通信的App,可以使用智能手机等便利的移动终端读取温湿度数据,从而实现低成本记录、传输、监测数据。Aiming at the problems of high cost and high energy consumption of existing temperature and humidity monitoring systems,a low energy consumption temperature and humidity recording system is designed.The system is based on Near Field Communication(NFC)and temperature and humidity sensing technology.The hardware part is mainly composed of temperature and humidity sensor module,NFC label module,Real Time Clock(RTC)clock module and main control chip.Each module is powered by lithium battery.The system provides effective charging management.The main control chip outputs current to NFC tag and other modules through Input Output(IO)port to reduce energy consumption.At the same time,in order to facilitate access to the temperature and humidity records,an app based on NFC communication is designed,which can read the temperature and humidity data with smart phones and other convenient mobile terminals,so as to achieve low-cost data recording,transmission and monitoring.
