Home Carbon Footprint Tracker Kit with ESP32 + Sensor
Home Carbon Footprint Tracker Kit with ESP32 – Real-Time Emissions Dashboard for Your Entire Household
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Turn your home into a precision carbon monitoring station. This kit brings together an ESP32, a PZEM-004T energy meter, and two YF-S201 flow sensors to capture electricity, gas, and water usage in real time. The on-board microSD and DS3231 RTC timestamp every datapoint, while the OLED displays a dashboard of daily carbon emissions—no cloud service or recurring subscription required. You get a self-contained, privacy-first environmental logger that runs continuously off a single 12V adapter.
What You'll Build
You'll assemble a standalone device that clamps onto your home's utilities. The ESP32 reads electricity parameters via Modbus RTU from the PZEM-004T, counts pulses from gas and water flow sensors, and applies India-relevant emission factors to output CO₂e in kilograms. All data is written to a CSV file on the SD card with precise timestamps, and the OLED gives you a live summary. The entire unit fits inside the included enclosure box, ready to be mounted near your distribution panel.
What You'll Learn
- Interfacing an industrial energy meter (PZEM-004T) with ESP32 over Modbus RTU, including register mapping and CRC validation
- Calibrating and reading YF-S201 flow sensors for both gas and water lines, and converting pulse counts to volume
- Applying IPCC and CEA emission factors to convert utility consumption into daily carbon dioxide equivalent (CO₂e)
- Building a timestamped data logger with DS3231 RTC, microSD storage in FAT32, and designing an OLED dashboard with real-time metrics

Who This Kit Is For
Engineers and graduate students in B.Tech ECE/EEE programs who need a hardware-in-the-loop carbon monitoring project for final-year submissions. Sustainability professionals seeking an at-home audit tool without vendor lock-in. Participants in Smart India Hackathon challenges focused on energy efficiency, and CBSE Class 11-12 science students exploring environmental sensor networks. The advanced complexity also matches capstone expectations at IITs, NITs, VIT, and BITS Pilani.
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, which walks you through circuit assembly, firmware upload, and calibration step by step. If you still need help, message us on WhatsApp—we respond within hours.
Can I track only electricity, or all three utilities?
The full kit includes sensors for electricity, gas, and water, so you can monitor all three. You can also configure it to monitor only the utilities that are relevant to your household.
Does this kit require any cloud subscription?
No. All data stays on the microSD card and the OLED. There is no dependency on cloud services, and you retain full control over your household's consumption data.
What emission factors does the dashboard use?
The AI companion helps you hardcode India-specific emission factors (from CEA or IPCC) directly into the ESP32 firmware during setup. You can update these factors any time via a simple code edit.
PZEM-004T electricity + gas flow meter + water flow meter calculate daily household carbon footprint on dashboard.
