DHT22 & BMP280 Kit
Create Animated Gauges & Charts: ESP32 LVGL GUI Framework Kit with DHT22 & BMP280
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform raw sensor data into polished, touch-responsive dashboards. This kit teaches you to design, code, and deploy a complete environmental monitor with the LVGL professional graphics library on ESP32. You'll solder, assemble, and program a standalone device that feels like a commercial product.
What You'll Build
You'll create a portable, enclosure-mounted instrument that reads ambient conditions and displays them on a 2.4-inch TFT touchscreen. Animated analogue-style gauges for temperature and humidity, a scrolling pressure chart, and tactile buttons let you switch views and toggle settings. The final product is ready for hackathon demos, college exhibition, or your personal lab bench.
What You'll Learn
- Architect LVGL widgets - gauge, chart, button, label - and bind touch events to them
- Integrate DHT22 (1-wire) and BMP280 (I2C) sensors, reading real-time environmental data
- Manage ESP32 memory and DMA channels for smooth LVGL rendering without flicker
- Calibrate sensor readings, format display labels, and structure clean, modular code in Arduino IDE

Who This Kit Is For
Advanced hobbyists and B.Tech ECE/EEE students working on embedded systems will find this kit immediately useful. It is especially suited for Smart India Hackathon participants who need a ready-to-integrate GUI front-end for IoT prototypes, and for final-year project groups at IITs, NITs, and VIT seeking a professional-grade human-machine interface without weeks of component sourcing.
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. It can debug your code, clarify wiring, and suggest LVGL layout improvements specific to this kit. You can also drop a WhatsApp message for human assistance during business hours.
Do I need prior experience with LVGL or ESP32?
We recommend basic C/C++ familiarity, but the AI companion walks you through every LVGL configuration and widget creation. Most advanced students finish the build in a single weekend, even without LVGL experience.
Can I customize the gauge and chart designs?
Yes. The AI companion will help you change colors, ranges, and widget layouts. The kit's GitHub repository includes template files you can fork for your own projects or integrate with other sensors.
Will this kit help me with my final year project submission?
Absolutely. The documented code, circuit schematics, and assembled enclosure give you a complete project-report deliverable that demonstrates embedded GUI development, multi-sensor integration, and real-time data visualisation.
LVGL graphics library on ESP32 renders animated gauges, charts and buttons on 2.4in TFT touchscreen.
