Smart Energy Meter Monitoring with IOT


The traditional way of monitoring electricity consumption involves manual meter readings, a process that is both time-consuming and prone to errors. With advancements in IoT (Internet of Things) technology, we now have the capability to make this process more efficient and accurate. This article explores the features and benefits of an IoT-based energy meter, a smart device that allows you to monitor your electricity usage and costs in real-time over the internet.

What is an IoT Energy Meter?

An IoT energy meter is a smart meter equipped with a microcontroller and a WiFi module. It measures the electricity consumed by your household or business and transmits this data to a web application. This enables users to monitor their energy consumption and associated costs from anywhere, at any time.
