ESP32 Home Energy Usage Indicator

Project Overview

Visualize relative power usage from a protected low-voltage demonstration circuit.

Objectives & Learning Outcomes

Signal calibration, current measurement and chart interpretation

Required Hardware

ESP32, isolated low-voltage current sensor demonstrator, OLED

Suggested Build Stages

1. Review the components and create a low-voltage wiring plan.
2. Assemble the prototype and test each sensor or module individually.
3. Implement firmware, display or communications in small verified steps.
4. Integrate the modules and document operating states and failures.
5. Run validation tests and prepare demonstration documentation.

Testing & Validation

Compare readings across controlled low-voltage loads; avoid mains handling.

Suggested Deliverables

Working demonstration, wiring diagram, commented firmware, test observations, component list, project report outline and presentation outline.

Educational project concept. Verify circuit values, actual component compatibility and safe operating limits before assembly. Illustrations are representative, not exact build photographs.
