IoTMajor project

IoT Smart Energy Monitor

An ESP32-based sensor node reads current and voltage, publishes readings over MQTT, and stores them in a time-series database. A Grafana dashboard shows live usage, daily totals and alerts for unusual consumption.

Level: Major project
Delivery: 5–7 working days
Stack: ESP32, Arduino C++
Best for: Final-year B.Tech / B.E. (ECE, EEE)

Features

ESP32 firmware for current and voltage sensing
MQTT publishing with reconnect handling
Time-series storage in InfluxDB
Live and historical dashboards in Grafana
Threshold alerts for unusual usage
