Project Overview
A complete IoT-based energy monitoring solution that measures real-time voltage, current, power, and energy consumption of household appliances. The system uses an ACS712 current sensor and a voltage divider to measure AC parameters, processed by an ESP32 that displays live data on an OLED screen and uploads readings to a cloud dashboard every 30 seconds.
Household electricity wastage is a major concern due to lack of real-time visibility into device-level energy consumption. Consumers have no way to identify high-consumption appliances without smart metering.
An ESP32-based energy monitoring node measures current and voltage, calculates instantaneous power and cumulative kWh, displays data locally on OLED, and pushes readings to a cloud platform. Alerts are triggered when consumption exceeds thresholds.
