Interactive GPS Sensor Heatmaps - Arduino Nano + DHT22 Kit
Build Your Own GPS-Enabled Environmental Sensor Heatmap - Arduino Nano + DHT22 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.
Walk across your campus while a handheld device silently stamps GPS coordinates onto temperature, humidity, and air quality readings every second. Back at your desk, one Python script turns that CSV into an interactive Folium heatmap you can share with your research guide. This kit replaces guesswork with ground truth - exactly what urban heat island studies, agricultural microclimate surveys, and pollution monitoring demand.
What You'll Build
You will assemble a portable, LiPo-powered sensor logger inside a waterproof enclosure. The Arduino Nano reads the DHT22 and MQ-135, timestamps each reading via the DS3231 RTC, tags it with location from the NEO-6M GPS, and writes a clean CSV row onto a microSD card. After the field survey, you pull the SD card, run our annotated Python script, and generate an HTML leaflet map where colour intensity reveals hotspots of temperature or CO? - ready for your report or dashboard.
What You'll Learn
- Synchronise GPS NMEA sentences with Arduino Nano and parse latitude/longitude in real time
- Interface the DS3231 RTC over I2C for microsecond-accurate timestamps
- Structure clean CSV data on microSD - fixed columns, no corruption on power loss
- Post-process raw CSV files with Python and Folium, rendering circle-markers that scale by sensor value

Who This Kit Is For
B.Tech ECE/EEE students tackling Smart India Hackathon challenges around environmental sensing. Final-year project groups at IIT, NIT, VIT, or BITS who need a reproducible data-logging pipeline. Research assistants mapping air quality across a campus, and ATL mentors demonstrating IoT+Pytho integration to senior batches. If you've already tinkered with Arduino and are ready to bridge hardware with data science, this kit will sharpen your edge.
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 box to start a chat with our AI build companion; it's trained on every solder joint and line of code in this kit. If you need a human touch, reply on WhatsApp and our engineering team will jump in.
Can I use this to track pesticide drift on a farm?
Absolutely. The MQ-135 detects ammonia and benzene families, common in pesticide evaporation. Log data while walking field perimeters, then run the Python script to generate a concentration heatmap you can hand to an agronomist.
How do I share the interactive heatmap with my project guide?
After running the script, you'll get an HTML file that works in any browser - no server needed. Upload it to your college drive, embed it in a report, or host it on GitHub Pages. The map is fully zoomable and self-contained.
Do I need prior Python experience?
Basic familiarity helps, but the script is heavily commented and the AI companion walks you through installing Folium and Pandas. If you've run a Jupyter notebook before, you'll be fine.
GPS-tagged sensor readings stored to SD. Python post-processes CSV into interactive Folium heatmap HTML.
