Pet Activity Monitor Pro Kit with ESP32 & DHT22 – Pre-Cool Your Home Before Your Pet Arrives

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 walking into a sweltering room only to find it already cooled because your system learned your pet’s daily rhythm. This kit lets you construct an ESP32-based monitor that tracks pet movement through dual PIR sensors, logs temperature across three zones with DS18B20 probes, and activates a relay-controlled fan or cooler precisely when your pet is due back. You’ll solder, program schedule-learning logic, and give your home a pet-aware intelligence.

What You'll Build

A wall-mounted system that detects occupancy patterns, records temperature history on a microSD card with real‑time clock stamps, and displays live status on a 0.96‑inch OLED. The relay module switches a cooling appliance before your pet’s expected return, using data-driven predictions. Everything fits inside the included enclosure box, running on a 12V adapter you wire through the buck converter.

What You'll Learn

• Program the ESP32 to read multiple DS18B20 sensors via OneWire and monitor DHT22 ambient humidity
• Interface HC-SR501 PIR motion detectors, debounce signals, and manage multi‑zone detection
• Log occupancy and temperature data to microSD with DS3231 RTC timestamps for pattern analysis
• Implement a predictive algorithm that analyzes absence windows and triggers relay pre-cooling 15 minutes early
