Pet Activity Monitor Smart Kit with ESP32 + DHT22
Pet Activity Monitor Kit — ESP32 Matter Smart Home for Tracking Your Pet’s Environment
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Your pet’s health hinges on a stable environment — temperature swings or sudden movements can signal distress. With this kit, you’ll build a complete pet activity monitor that behaves like a native smart home accessory. The ESP32 runs Matter SDK to expose temperature readings from two DHT22 sensors, motion alerts from PIR sensors, and four relay-controlled appliances (like a fan or heater) as individual accessories on your Apple Home, Google Home, or Amazon Alexa app. No bridges, no cloud — just direct local control.
What You'll Build
You’ll assemble a wall-mounted enclosure housing an ESP32 board, dual temperature/humidity sensors, dual PIR motion detectors, a 4-channel relay module, and an OLED status screen. Once programmed with the open-source Matter firmware we provide, the system appears as separate sensors and switches on any Matter-compatible smart home platform. Monitor your pet’s room temperature, receive motion alerts when your pet is active, and trigger a fan or small heater automatically — all from your phone, even when you’re away.
What You'll Learn
- How to configure the ESP32 with the Matter SDK and commission accessories onto a Thread/Wi-Fi fabric
- Interpreting DHT22 temperature/humidity data and PIR motion triggers for pet activity patterns
- Controlling high-current appliances safely through a 4-channel relay module with flyback diodes
- Designing a power supply circuit using the LM2596 buck converter to step down voltage cleanly

Who This Kit Is For
This kit speaks directly to B.Tech ECE/EEE students tackling IoT lab projects, Smart India Hackathon teams, and hobbyists from IIT/NIT/VIT/BITS campuses who want a real-world Matter deployment. If you’ve already worked with Arduino and want to step into the Matter ecosystem, or if you’re building a home automation portfolio for campus placements, this project gives you a polished, interview-ready demonstration.
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 inside the box to activate the AI companion for step-by-step guidance, or drop us a message on WhatsApp — we’ll help you debug within hours.
Can this kit integrate with Apple HomeKit or Alexa?
Yes. The ESP32 runs Matter SDK, so it commissions as native accessories on any Matter controller, including Apple Home, Google Home, and Alexa. No hubs needed.
Do I need prior experience soldering or with Matter protocol?
Soldering is required, and the included iron and solder make it possible even for first-timers. For Matter, we provide pre-compiled firmware and a setup guide; prior experience with C++ or ESP-IDF helps but isn’t mandatory.
How do I power the system for continuous pet monitoring?
The kit includes a 5V 3A PSU that connects directly to the buck converter, then to the ESP32. You can leave it plugged in 24/7 — the enclosure is designed with ventilation for safe, long-term use.
Pet Tracking — ESP32 Matter SDK exposes 4 relays, temperature and motion as native Matter accessories.
