A Wireless Network Data Transmission Via MQTT Server

Abstract

With the development in technology, IOT is now becoming a common practice to communicate with day-today interacting appliance remotely using a portable device like computer or Smartphone which has internet connectivity. In researching areas, old methods of data collection such as recording parameters by hand with the support of manual timer should be replaced by the application of Internet of Things that allow high speed data transfer and communication between apparatuses. This thesis creates a prototype of Data Collection System with the support from Message Queuing Telemetry Transport which is needed for many Viet Nam manufacturers in industrial 4.0 era. The objective of the research is providing an automatic product that collect data immediately, analyze and visualize on a Local Area Network that later can be apply in production line of machining factory. Throughout the design process, connection between board to board, board to modules and board to MQTT servers are clearly clarified. The output of the thesis is a combination of data sending module, data receiving module and an html website displaying real-time information of the whole system.
