Self-Healing Encrypted Sensor Mesh Kit with ESP32 + DHT22

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

This kit lets you deploy an eight-node self-healing wireless sensor network where every temperature and humidity reading travels across the mesh under AES-128 encryption. Whether you're building a secure campus environment monitor, a smart agriculture edge network, or a prototype for industrial IoT, each node automatically finds the best path to the root and recovers from node failures without manual intervention.

What You'll Build

You'll assemble and program eight battery-powered ESP32 sensor nodes that form a self-organizing mesh using ESP-MESH protocol. Each node reads DHT22 data and relays encrypted packets to a root node connected to a dashboard display. The network automatically re-routes if a node goes offline, and all payloads are secured with a shared AES-128 key, making eavesdropping virtually impossible. The weatherproof enclosures let you deploy these outdoors for real-world sensor monitoring.

What You'll Learn

• Implement ESP-MESH protocol for self-healing multi-hop networking on ESP32
• Encrypt sensor payloads with AES-128 in C/C++ using mbed TLS
• Design low-power battery-operated nodes with 18650 cells and TP4056 charging
• Optimize mesh throughput and latency for real-time environmental monitoring
