IoT and MQTT based web monitoring of a solar living laboratory

Abstract

This paper describes the tools used for the web-monitoring of a solar energy living lab referred to as SOLLAB. A low-cost electronic control unit (ECU) developed internally is presented and its use as an IoT is discussed. Based on this affordable hardware, the open source MQTT protocol and Node-Red framework are performed to ensure data communication locally and further distant monitoring through internet. The overall hardware and software architecture and configuration are explained in the context of the SOLLAB.
