PZEM Home Energy Dashboard
PZEM Home Energy Dashboard — Build Your Own Cloud-Connected AC Power Monitor with ESP8266
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine plugging your home appliances into a meter you built yourself, then watching real-time power draw, daily kilowatt-hours, and electricity cost on a web dashboard—from anywhere. This PZEM-004T and ESP8266 kit turns your curiosity into a fully functional energy monitoring system, perfect for CBSE Class 12 physics projects, B.Tech mini-projects, or any maker eager to understand residential power consumption. No more guessing what your AC units cost; you’ll measure it directly and log trends over days and weeks.
What You'll Build
A compact AC power monitoring device that clamps onto any single-phase 230V appliance or circuit. The PZEM-004T sensor reads voltage, current, active power, power factor, frequency, and cumulative energy. The ESP8266 pushes this data over Wi-Fi to a cloud dashboard—you’ll see live watts, daily kWh, and estimated cost based on your electricity tariff. The included OLED displays essential parameters locally, so you have a portable energy diagnostic tool even without an internet connection.
What You'll Learn
- Interface the PZEM-004T over Modbus-RTU using TTL serial, decoding energy parameters programmatically.
- Program the ESP8266 to read sensor data, display on OLED, and transmit to a cloud platform like ThingSpeak.
- Design a web dashboard with gauges, charts, and cost calculators that update in real time over the web.
- Apply energy auditing concepts—measure standby power, peak loads, and daily consumption patterns in a home setting.

Who This Kit Is For
Ideal for CBSE Class 12 students pursuing physics investigatory projects on electricity, B.Tech ECE/EEE undergraduates building their minor project, and ATL Tinkering Lab mentors demonstrating IoT energy monitoring. Also perfect for Smart India Hackathon hardware track participants who need a reliable AC power metering sub-system. Even hobbyists curious about their home’s appliance-level consumption will find this kit a complete launchpad.
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?
Our AI companion provides step-by-step debugging; you can also message us on WhatsApp for direct help.
Can this kit measure 3-phase industrial power?
No, the PZEM-004T is designed for single-phase 230V AC systems only, up to 100A. For three-phase setups, you’d need three sensors, but this kit demonstrates the core method.
What cloud platform does the dashboard use?
The guide covers ThingSpeak by default (free MATLAB visualizations), but you can adapt the code to Blynk, Adafruit IO, or your own server.
Do I need a soldering iron?
No soldering is required—all connections are made on the breadboard with the included M-M jumper wires
PZEM-004T measures real AC power. ESP8266 posts to cloud. Web dashboard shows daily kWh and cost.
