WiFi Mesh Network 5 Nodes Kit with ESP32 and DHT22 – Master Mesh Routing and IoT Sensor Data

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

Picture a network that heals itself when a node fails, routing temperature and humidity readings through the strongest path automatically. With this kit, you’ll build exactly that—a five-node WiFi mesh using ESP32 microcontrollers and DHT22 sensors, all visualized live on an OLED display that shows which nodes are online and how messages hop across the network. It’s the perfect foundation for protocols-driven IoT projects, hackathon demos, and learning how distributed wireless systems work in the real world.

What You'll Build

You’ll assemble five wireless nodes that form a self-organizing painlessMesh network. Each node reads temperature and humidity from its DHT22 sensor and shares data across the mesh. A central OLED display shows the real-time topology—which nodes are active, their sensor values, and the routing paths messages take. You’ll finish with a fully functional, decentralized IoT sensor network that continues communicating even if one node drops out.

What You'll Learn

• Configure ESP32 microcontrollers for mesh communication using the painlessMesh library
• Implement multi-hop message routing so data traverses intermediate nodes to reach a gateway
• Interface I2C OLED displays to dynamically visualize network topology and sensor readings
• Build robust wireless sensor networks that self-heal when nodes disconnect—essential for IoT projects

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is designed for intermediate-level makers—ideal for B.Tech ECE/EEE students prototyping wireless sensor networks, teams at Smart India Hackathon working on IoT solutions, and ATL Tinkering Lab students exploring advanced communication protocols. If you’re in Class 11–12 with Arduino experience, you’ll grow your skills into distributed systems without getting lost in theory.

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.
