Energy Monitoring System based on IoT

Abstract

Today, electrical appliances at home and work have become indispensable assistants that create comfortable conditions for people. Automated and intelligent electricity meters are being introduced around the world to monitor and assess electricity use in every home and workplace. The paper proposes a system designed for remote monitoring of electricity consumption from anywhere in the world and sends e-mail notifications when energy consumption reaches the threshold value. This technique uses a WeMos wireless control module with an ESP8266 microcontroller using a Wi-Fi channel, which is built into the Internet of Things and allows you to measure the current consumption of the load connected to the 220V mains and transmit the measured value via Wi-Fi. The ACS712 current sensor measures the current consumption and also provides insulation between the load and the IoT module. The Adafruit IO free cloud service and the MQTT Dashboard Android mobile app are used to track energy usage, and the IFTTT cloud service links the data to SMS / email notifications.
