DESIGN AND IMPLEMENTATION OF REAL TIME ENERGY METER INCORPORATED WITH POWER ANALYZER
Abstract
ABSTRACT
A precise and timely knowledge of energy consumption is an essential requirement for enforcing any energy saving strategy. Measuring energy consumption in the building is the basic functionality of energy building management systems. The monitoring of energy consumption in buildings indirectly provides information about the user habits, kind of activities carried on by the inhabitants, prediction of the future energy consumption in building and many other proposes. This issue can be addressed during the design phase of a monitoring system. The study presents the design and implementation of a real-time energy meter incorporated with a power analyzer. The real-time power analyzer is a device designed to monitor electrical parameters (voltage, current, power, power factor, frequency, and energy) using an ESP32 microcontroller, a PZEM-004T module with a current transformer (CT), and other components. The data is displayed locally on a round TFT display, sent to a Firebase Realtime Database every 3 seconds, and logged every 10 minutes for analysis. A web page retrieves and displays the data in real time, enabling daily consumption analysis and comparison across days
