Deploy a Fully-Functional K3s Sensor Cluster on Three Raspberry Pi 4 Nodes

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Move beyond single-board projects and step into the world of lightweight Kubernetes and distributed sensor networks. This kit equips you to assemble a three-node cluster running K3s, where each Raspberry Pi 4 hosts a DHT22 sensor pod. Temperature and humidity readings stream into a lightweight distributed database, presenting you with a real-world edge-computing architecture — the same pattern used in smart agriculture, industrial monitoring, and IoT analytics.

What You'll Build

You’ll boot three Raspberry Pi 4 boards, set up a K3s cluster, deploy DHT22 sensor pods using containerised Python services, and persist readings into a distributed store (we suggest an InfluxDB or SQLite-based approach). By the end, you’ll have a dashboard or a Prometheus/Grafana instance showing live sensor data from all three nodes, with the ability to scale pods, roll updates, and handle node failures gracefully.

What You'll Learn

• Provision Kubernetes clusters with K3s on ARM64 — covering multi-master and worker node setup
• Containerise sensor logic; package DHT22 drivers and reporting in Docker containers that run as pods
• Implement a distributed data layer; decide between replicated SQLite, InfluxDB, or edge-friendly databases
• Monitor cluster health and sensor telemetry with real-world observability tools (Prometheus node exporter, Grafana dashboards)

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

B.Tech ECE and CSE students tackling final-year projects or Smart India Hackathon challenges in edge computing will find this kit a ready-made infrastructure. It’s also a practical training resource for ATL Tinkering Labs with advanced cohorts, and for engineering clubs at IITs, NITs, VIT, or BITS Pilani that need a reproducible Kubernetes sandbox. If you’ve built a standalone sensor project and now want to understand container orchestration, this is your next logical step.

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.
