Build a Robust 10-Node Bluetooth Mesh with ESP32 & DHT22 Sensors – Advanced IoT Communication Kit

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

Imagine a wireless sensor network where a temperature reading from one corner of a building hops across multiple nodes to reach a central monitor, even if some intermediate nodes go offline. With this kit, you’ll create exactly that—a ten-node BLE mesh using ESP32 boards, each capable of relaying sensor data with configurable TTL hop limits. You’ll see messages find the shortest path, test failover when nodes power down, and understand the backbone of modern industrial IoT and smart building systems.

What You'll Build

You’ll assemble ten independent sensor nodes, each with an ESP32 that broadcasts DHT22 temperature and humidity readings into a Bluetooth mesh network. Five nodes include the actual DHT22 sensor, while others act as relays. Using Espressif’s BLE mesh stack, you’ll set hop limits to control how far data propagates, then observe a self-healing mesh where data reroutes when a node is disconnected. By the end, you’ll have a working model of a scalable, low-power communication network that mirrors real-world deployments in warehouses, agricultural monitoring, and campus IoT.

What You'll Learn

• Implementing BLE mesh networking on ESP32 using the ESP-IDF framework and official mesh APIs
• Configuring message TTL (Time-To-Live) to limit hops and prevent network flooding
• Integrating DHT22 digital sensors for multi-point environmental data collection
• Debugging multi-node mesh behavior with serial monitors and understanding provisioning, proxy, and relay features

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is built for B.Tech ECE and EEE students tackling IoT communication labs, final-year capstone teams prototyping mesh networks, and participants in Smart India Hackathon challenges around wireless sensor deployment. It’s equally valuable for research scholars at IITs, NITs, VIT, and BITS Pilani who need a ready-to-deploy ten-node testbed for mesh algorithm experiments.

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.
