Smart Plug Energy Monitor Kit with Arduino Uno + LED
Smart Plug Energy Monitor Kit with Arduino Uno – Track Appliance Electricity Usage
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Ever wondered how much electricity your TV, fan, or phone charger really consumes? This kit turns an Arduino Uno into a smart plug energy monitor that displays real-time data on an OLED screen. You’ll build a plug-and-measure device that tracks watts, amps, and daily kilowatt-hours, helping you make smarter energy decisions at home.
What You'll Build
You’ll assemble a compact energy monitor that sits between any standard appliance and the wall socket. A clear OLED screen instantly shows live power in watts, current in amps, and accumulated daily energy in kWh. It’s like having a mini smart meter for every gadget in your house.
What You'll Learn
- Interface the PZEM-004T energy sensor with Arduino using serial communication.
- Read real-time electrical parameters – voltage, current, power, and cumulative energy.
- Drive a 0.96-inch OLED display to show dynamic measurements with clarity.
- Understand how Indian homes consume electricity and how to identify energy-hungry devices.

Who This Kit Is For
Ideal for CBSE Class 9-12 students building science projects on energy measurement. ATL Tinkering Labs and first-year B.Tech ECE/EEE students at IIT, NIT, VIT will find it an excellent hands-on sensor integration project. Suitable for ages 5-15 with adult guidance.
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?
Scan the QR code on the box to chat with our AI build companion, which knows every step. You can also reach us via WhatsApp or email for human backup.
Is it safe to use with mains-powered appliances?
The PZEM-004T uses a non-invasive split-core current transformer that clamps around an existing power cord — no direct wiring to 230V is needed. Always handle under adult supervision when plugging or unplugging appliances.
Do I need to write code from scratch?
No. We provide pre-written Arduino code with detailed comments. You just upload it using a USB cable, and the OLED immediately starts showing live readings.
Can I extend this to log data over time?
Absolutely. You can add an SD card module or connect it to an ESP8266 for Wi-Fi logging. The AI companion can suggest modifications and code changes for logging daily energy trends.
PZEM-004T measures real power of any appliance. OLED shows watts, amps and daily kWh.
