Pet Activity Monitor Advanced Kit with ESP32 + DHT22
ESP32 Pet Activity Monitor Kit: Track Your Pet’s Environment and Automate with Home Assistant
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Bring real-time pet monitoring to your smartphone. This kit lets you build a custom device that tracks temperature and motion in your pet’s area, then triggers fans, lights, or feeders through relays—all controllable via the Home Assistant app, even when you’re away. With two DHT22 sensors and two PIR motion detectors, you get granular data to keep your pet comfortable and safe.
What You'll Build
A compact monitoring unit that measures temperature, humidity, and motion, feeding data wirelessly to Home Assistant. The 4-channel relay module lets you automate a cooling fan, a light, or a feeding mechanism based on sensor readings. The 0.96-inch OLED displays live readings locally, while the ESP32’s native Home Assistant API ensures seamless smartphone control.
What You'll Learn
- How to flash ESP32 with ESPHome for direct Home Assistant integration without third-party bridges
- Reading environmental data from DHT22 sensors and motion events from HC-SR501 PIR sensors
- Designing a relay control circuit with flyback diodes and stable power using the LM2596 buck converter
- Displaying real-time sensor data on an OLED and building sensor-driven automations in Home Assistant

Who This Kit Is For
Ideal for CBSE Class 11-12 students building IoT projects, B.Tech ECE/EEE learners exploring home automation, and Smart India Hackathon participants designing pet-care solutions. Also suits ATL Tinkering Lab mentors guiding sensor integration and hobbyists seeking a reliable Home Assistant pet monitor.
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 to access the AI companion, which provides step-by-step debugging for this exact kit. For additional help, contact us on WhatsApp—we respond within hours.
Does this kit work with the Home Assistant mobile app?
Yes. After flashing the ESP32 with ESPHome, the device appears automatically in Home Assistant. You can view temperature, humidity, and motion status and toggle relays from the companion app on Android or iOS.
Can I power the kit and relays from a single supply?
The LM2596 buck converter steps down a 12V DC adapter (not included) to 5V for the ESP32, while the relays can share the same 12V source. The included build guide shows the exact wiring.
What if a sensor fails?
We test every component before packing. If a manufacturing defect causes a failure within 7 days of delivery, we replace it at no cost.
Pet Tracking — ESP32 native HA API exposes 6 sensors and 4 relays. Control from Home Assistant mobile app.
