Smart Home Carbon Footprint Tracker Kit with ESP32 + Sensor
ESP32 Carbon Footprint Monitor Kit: Track Your Home’s Electricity, Gas & Water 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.
With this advanced kit, you’ll assemble a device that reads real-time electricity consumption from a PZEM-004T meter, counts pulses from a gas meter, and measures water flow via YF-S201 sensors. The ESP32 then computes your household’ daily carbon output using emission factors, displays it on an OLED screen, and logs everything to microSD for long-term analysis.
What You'll Build
A wall-mounted monitor that tracks and displays your home's daily carbon output, broken down by electricity, gas, and water. You’ll see live kilowatt readings, flow litres, pulse counts, and kilogram CO₂ on the OLED, while the microSD stores time-stamped data for trend analysis and sustainability reporting.
What You'll Learn
- Interfacing Modbus energy meters (PZEM-004T) with ESP32 for real power and energy readings
- Reading pulse inputs from gas meters and flow pulses from water sensors using interrupt pins
- Logging time-stamped data with DS3231 RTC onto microSD for historical analysis
- Calculating carbon emissions using standard conversion factors and displaying results on an OLED screen

Who This Kit Is For
The kit is ideal for B.Tech ECE/EEE students working on IoT or sustainability projects, participants of Smart India Hackathon building environmental monitoring prototypes, and advanced hobbyists who want a complete, pre-validated hardware stack. It also serves as a solid foundation for final-year project prototypes at colleges like IITs, NITs, VIT, and BITS.
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 to open the AI companion trained on this exact project; it provides step-by-step debugging. You can also message our WhatsApp support for fast human help.
Can this kit connect to an existing gas or water meter with a pulse output?
Yes, the YF-S201 flow sensor attaches to water pipes, and the ESP32 interrupt pins can read dry-contact pulse outputs from any compatible gas meter. All interfacing components are included.
How accurate is the carbon footprint calculation?
The PZEM-004T provides real power and energy readings with high accuracy, and water flow sensors are calibrated for typical flow rates. The embedded emission factors can be updated to match India's CEA grid factor or any global reference.
Do I need any other tools or equipment?
No extra tools are required. The kit includes a soldering iron, solder wire, and an enclosure. You only need a computer to program the ESP32.
PZEM electricity and gas meter pulse counter and water flow calculate daily household carbon output.
