摘要
设计了一种基于NB-IoT的低功耗物联网温度监测系统。利用温度传感器实时采集环境温度,MCU通过I/O口实时获取温度传感器数据并打包,经串口发送给NB-IoT通信模块,NB-IoT通信接入运营商网络,将数据上传至云平台,本地应用软件接入云平台获取温度数据进行展示应用。实验结果表明,该设计具有较高的应用推广价值。
In this paper,an embedded low-power NB-IoT temperature monitoring system is designed.The temperature sensor is used to collect the ambient temperature in real time.The MCU obtains the temperature sensor data in real time through the I/O port and packs them,and sends them to the NB-IoT communication module through the serial port.The NB-IoT communication module is connected to the cellular network,and the data is uploaded to the cloud platform,and the local application software is connected to the cloud platform to obtain the temperature data for display and application.The experiment results show that the design has high application value.
