Fei Ling, Juncheng Qing, Lei Tian · International Journal of Frontiers in Sociology · 2020
The designed data collection system could collect the data by each IoT node device through the MQTT protocol, display the data through the web client and remotely control the switch of the device. When the network is unavailable, the Bluetooth client could display the data and control the function of the device switch. Among the IoT node devices. In the wireless network environment, the devices upload data to the MQTT server with the WiFi module. Without a wireless network, the data would send to devices hrough the LoRa module to implement data and instructions.
