Monitor 3-Phase Power in Real Time with Arduino Mega Kit

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

You'll wire three ZMPT101B voltage sensors and three ACS712 20A current sensors to an Arduino Mega, then write code that calculates and displays per-phase and total kilowatts in real time — exactly what an industrial energy meter does. It's a hands-on way to grasp how factories, data centers, and commercial buildings monitor energy consumption without getting lost in high‑voltage complexity.

What You'll Build

A portable 3‑phase power monitor. A bright 16×2 LCD shows voltage, current, and real power (kW) for each of the three phases, plus the total system power. Use it to audit energy usage in your school lab, workshop, or even at home if you have a 3‑phase connection. It's self‑contained and safe to operate when assembled correctly.

What You'll Learn

• How to safely interface AC voltage and current sensors with an Arduino
• Calculating real power in kilowatts from instantaneous voltage and current samples
• I2C backpack integration for LCD to reduce wiring clutter
• Deploying a meter‑class measurement system on a microcontroller
