Whole Home Energy Dashboard Kit with Arduino Mega
Monitor Your Entire Home Energy on a TFT Dashboard with Arduino Mega
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Bring real-time circuit-level energy awareness into your home with a custom dashboard that logs every watt-hour. This kit equips you to build a three-channel monitor that samples current from any three loads—like a geyser, kitchen line, and study room—calculates cumulative energy consumption, timestamps readings via an RTC, logs them to a microSD card, and displays instant power, energy, and current on a vibrant TFT screen. Perfect for serious home automation tinkerers and engineering capstone projects looking to move beyond blinking LEDs.
What You'll Build
You will assemble a self-contained energy dashboard that continuously tracks three independent AC circuits. The display cycles between per‑circuit real‑time current, power, and total watt‑hours used, while the SD card stores all data points with precise timestamps for offline analysis. You’ll have a permanent tool to audit appliance consumption, identify phantom loads, or fine‑tune your home solar/battery backup sizing.
What You'll Learn
- Non‑invasive AC current sensing using ACS712 modules and safe low‑voltage wiring around live circuits
- Precision timekeeping with DS3231 RTC, including automatic compensation for power loss
- Structuring CSV log files on an SD card for import into spreadsheets or custom parsers
- Designing a modular TFT user interface that manages multiple data screens with physical button toggling

Who This Kit Is For
This advanced kit is designed for B.Tech ECE and EEE students tackling capstone projects, Smart India Hackathon teams needing a reliable energy-monitoring IoT node, and hobbyists from IIT, NIT, VIT, BITS, or home labs who want a production‑grade dashboard. If you have previously built intermediate Arduino projects and are comfortable with soldering and handling AC mains safely, you are the ideal maker.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Open the AI companion first—it can diagnose 90% of issues from photo uploads. If you need a human touch, ping us on WhatsApp and we’ll help you wire the current sensors or calibrate the readings.
Can I add more than three current sensors?
The Arduino Mega has enough analog inputs and I/O to expand up to five ACS712 modules, and the companion guide includes pin‑mapping and code blocks for scaling beyond three circuits.
How do I safely connect this to my home’s AC mains?
The ACS712 modules clamp around the live wire only; you never cut into the mains. We provide a full isolation diagram and mandatory safety checklist that every builder must review before powering on.
Can I import the SD card data into Excel or Python?
Absolutely. The logged CSV file is formatted with timestamp, circuit ID, current, power, and energy columns. The AI companion shows a Python script to parse and graph the data, and Excel can open it directly.
Three ACS712 sensors monitor three circuits. Calculates per-circuit watt-hours, logs to SD with RTC, shows on TFT.
