Carbon Budget Tracker Dashboard Kit with ESP32 + Sensor
Monitor Your Carbon Budget in Real Time with the ESP32 Carbon Tracker Dashboard 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 build a system that tracks electricity, water, and gas usage in real time, converts each into carbon dioxide equivalents, and pushes everything to a live Grafana dashboard — the same kind of environmental monitoring stack used in green building certifications and campus sustainability audits. For engineering students and hackathon teams, this kit compresses months of sensor integration and dashboard design into a single weekend.
What You'll Build
A multi-utility carbon budget tracker that pulls data from a PZEM-004T energy meter and two YF-S201 flow sensors (for water and gas), timestamps everything with a DS3231 RTC, logs to an SD card, and feeds a Grafana instance. The dashboard shows daily CO₂ totals, per-utility breakdowns, and trend lines that make your lab or hostel’s environmental impact tangible and presentation-ready.
What You'll Learn
- Interfacing the PZEM-004T energy meter with ESP32 over Modbus RTU to capture real-time voltage, current, power, and cumulative energy.
- Calibrating YF-S201 hall-effect flow sensors for water and gas, then normalizing pulse counts to litres or cubic metres.
- Building a time-synchronised data logger using a DS3231 RTC and MicroSD module — essential for accurate carbon accounting.
- Structuring MQTT payloads and setting up a Grafana dashboard with Prometheus or InfluxDB to visualise cumulative CO₂ emissions.

Who This Kit Is For
This advanced kit is designed for B.Tech ECE and EEE students working on embedded systems or energy monitoring capstone projects. It’s equally a strong fit for Smart India Hackathon teams building sustainability dashboards, and for PG students in IITs, NITs, VIT, or BITS Pilani who need a ready-to-deploy sensor-to-dashboard pipeline for research or lab demonstrations. If you’ve already worked with an Arduino or basic IoT projects and want to move to real‑world carbon accounting, this is your next step.
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 kit to launch our AI companion. It’s trained on the exact wiring, code, and dashboard setup you’ll need. If you still need human help, reach out on WhatsApp and a Compoden engineer will jump in.
Do I need a dedicated server to run Grafana?
No, a laptop running Linux or Windows with Docker is fine during development. For long‑term monitoring, a Raspberry Pi 4 (not included) works perfectly and is what we use in our test bench.
Can this kit measure three‑phase electricity?
The PZEM‑004T is designed for single‑phase AC mains (up to 100A). For a three‑phase setup you would need two additional PZEM‑004T modules (not included) and modify the firmware accordingly. Our AI companion can guide you through that extension.
How do I calibrate the YF‑S201 for gas flow if it’s originally a water flow sensor?
The YF‑S201 works with any clean, non‑corrosive fluid. For gas, you must place it in a sealed section, apply the appropriate conversion factor (pulses per litre vs. cubic metre), and adjust the code. The AI companion includes a calibration walkthrough for both water and a typical biogas line.
