Pi 5 Smart City Noise Pollution Map
Build a Live Noise Pollution Heatmap with Raspberry Pi 5 and ESP32
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Deploy four ESP32 microphone nodes across your model city and watch dB readings stream to a Raspberry Pi 5 every few seconds. The Pi runs an interpolation engine to generate a colour-coded noise pollution map that refreshes every five minutes, giving you a living view of urban sound intensity. From traffic hotspot identification to industrial zone monitoring, this kit turns raw decibel data into actionable visual intelligence.
What You'll Build
A fully functional noise monitoring network that visualises sound levels across distinct city zones. Each MAX9814-based node captures ambient noise, the Pi 5 aggregates the data, and a heat map overlay pinpoints areas exceeding safe decibel thresholds. The system updates continually, showing how sound ebbs and flows in real time.
What You'll Learn
- Set up a multi-node ESP32 sensor network and stream real-time dB data over Wi-Fi
- Implement linear interpolation algorithms to generate spatial heat maps from discrete sensor inputs
- Configure an NVMe SSD with an M.2 HAT+ for high-speed data logging on Raspberry Pi 5
- Design a dashboard to visualise live noise pollution trends and export logged records

Who This Kit Is For
Ideal for B.Tech ECE and EEE students building smart city proof-of-concepts, and for CBSE Class 11–12 learners exploring IoT in ATL Tinkering Labs. It’s a strong entry for Smart India Hackathon challenges on urban noise pollution, enabling teams from IIT, NIT, VIT, or BITS to deliver a working prototype within a day.
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?

Can I scale the network beyond four microphone nodes?
Yes. The ESP32 code and Pi 5 interpolation software are designed to accept additional nodes. You can expand by adding more ESP32+MAX9814 pairs and updating the configuration file.
How accurate is the noise heat map interpolation?
The built-in linear interpolation algorithm produces a smooth gradient suitable for smart city demonstrations. For higher precision, the AI companion can guide you through replacing it with a kriging or IDW model.
Can I log data to the cloud instead of the NVMe SSD?
Absolutely. The companion app includes optional modules to push data to Firebase or InfluxDB Cloud. The NVMe SSD serves as reliable local storage, but you can easily route feeds to any cloud endpoint.
Multiple microphone nodes stream dB readings to Pi 5 — interpolation model generates noise pollution heat map updated every 5 min.
