ESP32 Pet Heating Scheduler Kit - DHT22 & PIR Sensors
Build a Self-Learning Pet Heating Controller 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.
Turn your ESP32 into a pet-aware heating controller that watches for motion and temperature, then learns when to warm your pet's enclosure automatically. By recording PIR activity over a week, the system builds a daily occupancy pattern and triggers the boiler relay precisely when predicted activity peaks in cooler temperatures. No more manually toggling heaters-let the kit adapt to your pet's real routine.
What You'll Build
You'll assemble a wall-mounted unit with two PIR sensors to detect pet movement, dual DHT22 sensors for temperature/humidity feedback, and a DS3231 real-time clock to timestamp occupancy data onto a MicroSD card. After a seven-day learning phase, the 0.96-inch OLED displays a learned heating schedule that activates a 4-channel relay module during predicted active periods, keeping your pet's resting area at an optimal temperature regardless of manual intervention.
What You'll Learn
- Design a multi-sensor IoT node with ESP32 communicating over I2C (DS3231, OLED) and SPI (MicroSD)
- Implement a simple on-device pattern recognition algorithm that transforms PIR logs into a daily occupancy histogram
- Calibrate DHT22 sensors and integrate relay control with hysteresis to maintain temperature setpoints
- Assemble and solder a permanent prototype on PCB boards in a compact enclosure, including power regulation from 12V

Who This Kit Is For
Final-year B.Tech ECE/EEE students prototyping smart home solutions, IoT enthusiasts building data-driven pet care systems, and working engineers refining edge-ML concepts will find this kit ideal. It's also a strong match for Smart India Hackathon teams and ATL Tinkering Lab mentors wanting an advanced, real-world automation project that ties sensor fusion with predictive relay control.
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 start your AI companion, which walks through every connection and code block. If you need human help, our WhatsApp support line covers the exact same project, no generic scripts.
Does the system work without an internet connection?
Yes, all logic runs entirely on the ESP32. The learning algorithm, data logging, and relay control happen offline. You only need Wi-Fi if you later want to add remote monitoring.
Can I use this kit for multiple pets or separate zones?
The kit includes two PIR and two DHT22 sensors. You can place them in different areas and modify the firmware to track and heat two independent zones, each with its own learned schedule.
How accurate is the learned schedule after seven days?
After one week, the occupancy histogram captures 90% of your pet's regular active periods. The relay trigger includes a configurable tolerance window, so a few days of data already produce a practical heating routine that improves with continued logging.
Pet Tracking - Records occupancy patterns over a week and learns a heating schedule. Controls boiler relay based on prediction + DHT22.
