Comparison of Cloud IoT Platforms for Smart Metering Solution Based on NodeMCU

摘要

This article describes design and implementation of a smart metering system based on cheap NodeMCU board which was connected to the cloud via smart IoT Gateway. The designed system consists of smart meter device that wirelessly transmits data to IoT cloud platform, where they are processed and analyzed. We compared two use cases that were using services from Microsoft Azure and IBM Bluemix. The conclusion summarizes advantages and disadvantages of the designed IoT solutions.
