ESP32 Smart AC Power Monitor with Automatic Power Factor Correction — Project Showcase

[Kumareshan2006]

Hi everyone,

I've built an ESP32-based smart AC power monitor with automatic power factor correction and I'm looking for feedback and suggestions from the community.

What it does:
- Measures Voltage & Current RMS, Real/Reactive/Apparent Power, Power Factor, Frequency, Crest Factor, and Impedance
- Automatically switches capacitor banks to correct poor power factor
- Cloud integration via Blynk and Adafruit IO
- Built on ESP32 WROOM-32

Technical details:
- Bare-metal ESP-IDF v5.x (converted from Arduino)
- Register-level GPIO, ADC, and timer control
- AC mains measurement with RMS calculations

Looking for collaborators, code reviewers, and any suggestions to improve the design or firmware. Happy to discuss any part of the implementation.

Thanks!
