Auto Light Energy Saver Pro Kit with ESP32 + DHT22
Auto Light Energy Saver Pro Kit: ESP32 Predictive Home Energy Control
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 home that watches your daily routine for a week, then automatically heats your rooms exactly when you need them — no timers, no manual switches. With this kit, you'll build a predictive boiler controller that logs occupancy via PIR sensors, records temperature and humidity trends, and schedules relay activation based on learned patterns. Perfect for India’s winter mornings, where smart heating can cut energy bills by over 30%.
What You'll Build
You'll assemble a compact, wall-mountable smart energy node that monitors two rooms for motion and environmental data for seven days. The ESP32 writes logs to a microSD card, then uses the data to predict when each room needs heating. It controls a boiler or heater via the 4-channel relay, displaying real-time status on the OLED. The system adapts to changes — if your family's schedule shifts, it relearns automatically.
What You'll Learn
- Implementing a predictive scheduling algorithm from week-long occupancy logs
- Interfacing multiple I2C sensors (DHT22, DS3231 RTC, OLED) over ESP32
- Data logging with microSD and FAT32 file management on Arduino framework
- Industrial-grade relay control with schedule-based automation

Who This Kit Is For
This advanced project kit is built for engineering students tackling Smart India Hackathon themes on energy efficiency, B.Tech ECE/EEE final-year projects, and ATL tinkering lab mentors guiding IoT innovation. It assumes prior experience with ESP32 programming and soldering — perfect for makers in IIT, NIT, VIT, BITS campuses looking to deploy real-world predictive automation.
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.

Does this kit need a Wi-Fi connection after deployment?
No. All prediction and logging happens locally on the ESP32. Wi-Fi is needed only if you later add remote monitoring via MQTT — the kit’s base design works offline.
Can I control more than one boiler with this kit?
Yes. The 4-channel relay supports up to four separate loads. You can assign different rooms or zones to different channels and let the predictive algorithm manage each independently.
How accurate is the predictive heating schedule?
After a full 7-day logging period, the algorithm maps occupancy patterns with over 90% accuracy under stable routines. It re-adjusts if patterns shift, ensuring minimal wasted energy.
Energy Saving — Records occupancy for 7 days. Learns heating schedule and controls boiler relay predictively.
