An Open Source LoRa Based, Low-Cost IoT Platform for Renewable Energy Generation Unit Monitoring and Supervisory Control

SCADA provides real-time system monitoring by constant communication and data exchange between various devices to achieve visualization logging. Presently, in industrial systems, commercial systems are being used for control. These can be expensive, as such only afforded select industries. Even at these costs, the face some challenges, which include interoperability scalability issues. Research has shown that problems solved introduction of low-cost materials open-source software all levels processes. This paper proposes an open source, Internet Things (IoT)-based employs IoT architecture functions. The proposed is improvement existing solutions eliminating cloud based platforms introducing a single machine system. solution increases robustness while reducing costs. prototype consists voltage current sensors, Arduino Uno microcontroller Raspberry Pi. sensors acquire from monitored unit. receives processes them transmission Pi using LoRa technology. At Pi, local Chirpstack platform displays measured Grafana dashboard monitoring, stored InfluxDB database. For validation purposes, designed, developed, set up monitor panel voltage, battery solar photovoltaic results obtained experimental set-up compared with test physical digital multimeters. presented this low-cost, scalable interoperable This, therefore, makes alternative especially applications. deployed large appropriate upgrades customization. main contribution research design development performs functions proprietary very features limitations traditional systems.
