ESP32 Sensor Network Map Kit - Mesh Topology Visualizer
Build a Self-Healing Sensor Mesh: ESP32 Network Map Kit with Live Topology Display
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
You'll assemble eight ESP32 nodes-each reading temperature and humidity via DHT22-that automatically form an ESP-NOW mesh network. The central hub draws a live topology map on a 1.8-inch TFT screen, showing every connection link and signal strength. This kit makes the invisible mesh routes tangible, perfect for B.Tech final-year projects, Smart India Hackathon prototypes, or anyone diving deep into decentralized IoT systems.
What You'll Build
A fully functional, self-organizing sensor network. Eight battery-powerable ESP32 nodes transmit environmental data over the ESP-NOW protocol to a dedicated hub. That hub continuously updates a graphical network map on the ST7735 TFT, revealing which nodes are currently connected, the signal quality between them, and how the mesh reconfigures if a node drops off. The result is a real-time interactive dashboard that visualizes mesh theory in a compact physical layout.
What You'll Learn
- ESP-NOW peer-to-peer communication and mesh topology logic without relying on Wi-Fi routers
- Integrating DHT22 sensor readings into a distributed sensor array
- Driving TFT color displays (ST7735) for live network graph rendering
- Building resilient IoT systems with automatic topology discovery and failover paths

Who This Kit Is For
Engineered for advanced makers: B.Tech ECE/EEE students crafting their final-year IoT project, teams preparing for Smart India Hackathon, and researchers at IIT/NIT/VIT/BITS exploring decentralized wireless sensor networks. The kit also challenges CBSE Class 11-12 ATL tinkering lab students who are ready for a college-level autonomous mesh build.
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?
The included AI companion walks you through each step, from soldering the DHT22 modules to configuring ESP-NOW mesh logic. If you prefer human help, reach out via WhatsApp-our support team responds within a few hours.
Can this mesh network work without Wi-Fi?
Yes. ESP-NOW is a peer-to-peer protocol that operates entirely without Wi-Fi infrastructure or internet access. The mesh forms directly between ESP32 boards, making it ideal for off-grid and field deployments.
How many sensor nodes can I expand this to?
The kit's firmware supports 8 nodes natively on the TFT map. You can scale the mesh to more nodes by modifying the node-discovery code-the ESP-NOW library can handle up to 20 peers per device.
Do I need prior soldering experience?
Basic soldering skills are required to attach the DHT22 sensors and power inputs. The kit includes a soldering iron and wire, and the AI companion provides clear visual soldering guides to help you succeed.
