Pi Zero 2W Edge Inference MQTT Gateway Kit with Raspberry Pi Zero 2W + DHT22 — a beginner-level kit for teens.

Build an Edge AI MQTT Gateway with Raspberry Pi Zero 2W – Complete Kit

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 25 days.

Transform a Raspberry Pi Zero 2W into an edge inference device that runs a TensorFlow Lite model locally. Read environmental data from the DHT22 sensor, process it with a tiny machine learning model right on the Pi, and publish the inference results to an MQTT broker. You’ll build your first working bridge from on-device AI to a live IoT dashboard—exactly what smart factories, weather stations, and remote monitoring systems use today.

What You'll Build

You’ll assemble a compact gateway that samples temperature and humidity from the DHT22, feeds the readings into a pre-trained TFLite model, and pushes the predicted class or anomaly flag to any MQTT client. View the output on a smartphone dashboard app, a laptop, or even integrate it with Node-RED for alerts. It’s a production-grade pattern, made accessible with clear step‑by‑step guidance.

What You'll Learn

• Headless setup of Raspberry Pi Zero 2W and remote SSH access
• Wiring and reading DHT22 sensor data with Python
• Running TensorFlow Lite inference at the edge—using a model trained for environmental data
• Publishing and subscribing to MQTT topics, and building a real‑time monitoring pipeline

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Designed for CBSE Class 11–12 students diving into AI and IoT, B.Tech ECE/EEE first‑years building mini projects, Smart India Hackathon teams prototyping sensor‑to‑cloud systems, and ATL Tinkering Lab mentors who need a ready‑made edge AI kit. It assumes no prior machine learning experience—just curiosity and a laptop.

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.
