Case study: Implementing an industrial water management system with Eclipse IoT
summary
A working demo connects industrial flow meters to a cloud using Eclipse Kura on a Raspberry Pi gateway, Mosquitto as MQTT broker and simple Spring Boot services exposing REST; the gateway polls a PLC over Modbus RTU every 5s, reads two 16-bit registers, converts bytes to a 32-bit float and publishes protobuf payloads; hardware includes pump, inverter, pressure and temperature sensors and an HMI; system runs end-to-end with TLS and live UI updates.
