P2P Encrypted Sensor Mesh Variant 7 Kit with ESP32 + DHT22
ESP32 Encrypted Mesh Sensor Kit — Build a Self-Healing IoT Network with DHT22 and AES-128
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Deploy a private, encrypted sensor network across your facility without relying on a central router. This kit guides you through building eight ESP32 nodes that automatically form a self-healing mesh using ESP-MESH, with all DHT22 temperature and humidity data secured by AES-128 encryption in transit. Whether monitoring server rooms, greenhouses, or industrial spaces, you'll end up with a resilient IoT infrastructure that resists single points of failure.
What You'll Build
You'll build an eight-node wireless sensor mesh that routes data peer-to-peer, even if some nodes go offline. Each node reads temperature and humidity, displays data on paired OLED screens, and encrypts transmissions so only authorized nodes can interpret the stream. The network self-organizes, healing around broken links without manual intervention — exactly how tactical IoT deployments operate.
What You'll Learn
- Configuring ESP-MESH and understanding its self-healing routing algorithm
- Implementing AES-128 encryption on ESP32 for sensor data in transit
- Powering ESP32 nodes with 18650 Li-ion cells and designing battery management circuits
- Integrating DHT22 sensors, OLED displays, and waterproof enclosures for real-world deployment

Who This Kit Is For
Engineers, researchers, and advanced hobbyists building resilient sensor networks. Ideal for final-year B.Tech ECE/EEE projects, M.Tech IoT specializations, Smart India Hackathon teams, and professionals prototyping industrial monitoring solutions. If you've tinkered with single ESP32 boards and are ready to tackle a distributed system with real encryption, this kit puts you on the fast track.
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 for the AI companion trained on this mesh project, or reach our team on WhatsApp. We'll walk you through mesh configuration and encryption debugging.
Do I need a WiFi router for the mesh to work?
No. ESP-MESH creates its own ad-hoc network; nodes communicate directly without a central access point. An existing WiFi network is only needed if you want to bridge mesh data to the internet.
Can I expand the network beyond 8 nodes?
Yes. The ESP-MESH protocol supports larger node counts, but this kit provides the parts for 8. You can
Eight ESP32 nodes form a self-healing WiFi mesh using ESP-MESH. All sensor data AES-128 encrypted in transit.
