Smart City PM2.5 Node Kit - Edge AI with Portenta H7 & LTE-M
Deploy an Intelligent Air Quality Node with Arduino Portenta H7 and LTE-M
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Most air quality nodes send raw data continuously, wasting power and cloud costs. You'll build something sharper: a solar-powered station that uses TensorFlow Lite on the Portenta H7's M7 core to classify pollution anomalies locally, then transmits only critical alerts via LTE Cat.M1. Ideal for dense urban monitoring, industrial fence-lines, or smart city pilots where every message must count.
What You'll Build
A rugged, weatherproof sensor node that measures PM2.5, PM10, CO2, temperature, and humidity. On-device TFLite models assess whether readings constitute a real pollution event. When an anomaly is flagged, the Cat.M1 GNSS shield sends a compact alert with location and sensor context to your cloud endpoint, while logging all data to microSD for later analysis.
What You'll Learn
- Deploy TensorFlow Lite for Microcontrollers on the Portenta H7's Cortex-M7 core with real sensor inputs
- Integrate PMS5003, MH-Z19B, and DHT22 into a multi-sensor fusion pipeline with RTC time-stamping
- Program event-driven LTE Cat.M1 transmission using the Portenta Cat.M1 shield and GNSS for location tagging
- Design a solar-battery power system with 18650 cells, TP4056 charging, and buck regulation for continuous outdoor operation

Why Buy This Kit Instead of Sourcing Parts Separately
| Factor | Sourcing Separately | Compoden Kit |
|---|---|---|
| Compatibility checks | You verify every part, shield pin-out, and I2C address | Pre-tested as a system: all sensors, shield, and power stage coexist without conflict |
| Build support | Forums and fragmented tutorials for each sensor | AI companion trained on this exact firmware stack and model quantization flow |
| Time to first working build | Days of hardware debugging and Mbed OS bring-up | Hours, with step-by-step guidance on TFLite integration and LTE provisioning |
| Shipping coordination | Multiple sellers, several delivery timelines | One shipment from Bengaluru in 3-5 days |
Who This Kit Is For
This kit is built for engineers and researchers driving India's smart city and environmental monitoring agendas. It fits final-year B.Tech ECE/EEE capstone projects at NITs, IITs, VIT, and BITS, as well as R&D teams prototyping pollution dashboards for municipal bodies or Smart India Hackathon finalists scaling their PoCs. If you need an industrial-grade node that treats LTE data as precious, this is your starting block.
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 inside the box to talk to the AI companion trained on this exact project, or drop us a message on WhatsApp. We'll help you debug sensor I2C bus conflicts or TFLite model deployment.
Does the kit include a SIM card for Cat.M1 service?
The SIM is not included because network providers vary by region. We provide a provisioning guide for Jio, BSNL, and Vi Cat.M1 plans suitable for IoT data.
Can I visualize data on a cloud dashboard?
Yes, the example firmware and AI companion show how to push alerts to ThingSpeak or AWS IoT Core using MQTT-SN. You'll have a live dashboard with geo-tagged events in under an hour after provisioning.
What PM2.5 range and accuracy does the PMS5003 support?
The PMS5003 measures 0-500 �g/m� with particle counts for 0.3, 0.5, 1.0, 2.5, 5.0, and 10 �m. The on-device anomaly model uses the ratio of these bins to distinguish dust spikes from actual pollution events.
Smart City - Portenta + Cat.M1 Shield + TFLite classifies air quality anomalies on M7. Sends only event alerts via LTE to cloud.
