Demo: Wireless sensor network for retrofitting production systems

This paper describes the prototypical implementation for demonstration purposes of a wireless sensor network for recording production parameters like temperature and acceleration for machine monitoring on machine tools. The data collection is done with devices and components from the low budget area, like a single board computer (SBC) and Adafruit Breakout Boards, as well as directly from the machine control via the communication protocol Open Platform Communications Unified Architecture (OPC UA). The message queuing telemetry transport (MQTT) broker is used for the transfer of the data packets. The collected data is collected by means of a time-series based database (InfluxDB) and visualized via a Grafana server.
