ESP32-H2 Kit
Keep Your HVAC Running Efficiently - Build a Thread Node Monitor with ESP32-H2
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Every AC, server room, or cold storage unit depends on stable temperature and humidity. This kit guides you through building a battery-powered ESP32-H2 Thread end device that reads a DHT22 sensor and transmits real-time data into a Thread mesh network - giving you wireless insight into HVAC performance without running a single new wire.
What You'll Build
You'll assemble a compact monitor that uses the ESP32-H2's native Thread radio to send temperature and humidity readings to any Thread border router. The whole circuit fits inside the included ABS enclosure, runs on a rechargeable LiPo cell, and can be mounted discreetly near air handlers, ducts, or return grilles for continuous telemetry.
What You'll Learn
- How to interface a DHT22 digital sensor with an ESP32-H2 and read accurate temperature/humidity values
- Configuring the ESP32-H2 as a Thread end device and joining an existing Thread network
- Implementing deep sleep with periodic wake-up to achieve ultra-low power consumption on battery
- Soldering the components onto a prototyping PCB and housing everything in a field-ready enclosure

Who This Kit Is For
This kit is perfect for CBSE Class 11-12 students exploring IoT and sensor systems, B.Tech ECE/EEE undergraduates building wireless sensor networks, and hobbyists curious about Thread mesh protocols. With adult supervision, ambitious young makers (age 10+) can assemble the hardware, while older students can dive into the code and network topology - making it a solid foundation for Smart India Hackathon prototypes or ATL Tinkering Lab projects.
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.

Do I need a separate Thread border router to use this node?
Yes - the ESP32-H2 is a Thread end device. You'll need an existing Thread border router (like a HomePod Mini, Google Nest Hub, or a second ESP32-H2 acting as a border router) to receive the sensor data and expose it on your IP network.
How long does the battery last?
With deep sleep and a transmission interval of about 1 minute, the 500 mAh LiPo lasts roughly 4-5 days on a full charge. You can adjust the reporting frequency in the firmware to extend battery life significantly.
Can I integrate this with Home Assistant or other platforms?
Absolutely. Once the node joins a Thread network, its data can be bridged via Matter-over-Thread and integrated into smart home platforms such as Home Assistant, Apple Home, or Node-RED. The kit provides the sensor endpoint; the integration is up to you.
HVAC - ESP32-H2 Thread node sends temperature and humidity into a Thread network. Low power periodic transmit.
