Design of air quality monitoring system based on Internet of Things

摘要

A kind of Ethernet remote monitoring and control system based on LM3S8962 is presented in this paper. This design has the advantages of stability and ultra-low power consumption. By transplanting LwIP protocol on the LM3S8962, to achieve a homemade weather station Internet connection and automatically obtain an IP address, the user through the mobile phone or a PC web browser to access the system WEB server through the web page display the temperature, humidity, voltage, PM2.5 and other sensor data, and network gateway can control sub-node peripherals use the control instruction which be uploaded to be sent to the sub-node, achieving wireless LAN to the Internet for remote monitoring and control system by ZigBee, the local LCD would display the parameters and IP addresses. Meanwhile, the system can also be used as a client, the collected data is uploaded to a common data center networking platform-yeelink website.
