Predictive Learning Thermostat Kit with ESP32 + DHT22
Predictive Learning Thermostat Kit – Build a Smart Heating System That Learns Your Routine Using 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.
Imagine a thermostat that doesn’t just respond to the current temperature but anticipates your home’s heating needs. This kit lets you construct a device that records room occupancy for 7 days using PIR motion sensors, logs environmental data, and then predictively controls a boiler relay—so the house is warm exactly when you need it, without manual schedules. Designed for engineering students and advanced makers, it’s a real-world IoT automation project that blends sensing, data logging, and on-device intelligence.
What You'll Build
You’ll assemble a fully functional predictive thermostat powered by an ESP32. Dual DHT22 sensors monitor temperature and humidity in two zones, while two HC-SR501 PIR modules detect movement. A DS3231 real-time clock ensures accurate timestamps as all data is stored on a microSD card. After a learning period, the ESP32’s algorithm activates a 4-channel relay to drive your boiler or heating appliance based on learned occupancy patterns. The 0.96-inch OLED displays current status, and everything fits inside the provided enclosure.
What You'll Learn
- Implementing on-device pattern recognition using ESP32 to predict home occupancy schedules
- Logging multi-sensor data to microSD with RTC-synchronized timestamps for training
- Designing reliable sensor fusion from PIR motion and DHT22 environmental inputs
- Soldering a complete prototype PCB and enclosing a mains-control project safely

Who This Kit Is For
This advanced kit is built for B.Tech ECE/EEE students developing capstone or Smart India Hackathon projects, and final-year engineers specialising in IoT. CBSE Class 12 students with strong electronics and programming fundamentals will also find it challenging, as will ATL Tinkering Lab mentors guiding predictive automation prototypes. If you’re at IIT, NIT, VIT, or BITS and need a project that demonstrates edge intelligence, this thermostat delivers.
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 chat with our AI build companion trained on every step of this thermostat project. If you need a human, WhatsApp support is included.
Does the kit require internet or cloud services?
The predictive algorithm runs entirely on the ESP32 using locally logged data; no cloud is mandatory, though you can add optional remote monitoring if desired.
Can the relay module control a geyser instead of a boiler?
Yes, the 4-channel relay can switch any resistive heating load up to 10A, so you can adapt the project for geysers, room heaters, or even AC units with minor code changes.
What coding skills are needed?
You’ll use Arduino IDE (C++), and the AI companion provides fully commented code for the learning algorithm, sensor reading, and relay control. Some soldering experience is assumed.
Records occupancy for 7 days. Learns heating schedule and controls boiler relay predictively.
