ESP32 Elderly Care Heat Scheduler Kit with DHT22 Sensors
Learn Occupancy Patterns and Automate Heating for Elderly Care 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.
This kit helps you build a system that monitors an elderly person's room occupancy and temperature, then learns a heating schedule to keep them comfortable while saving energy. By the end, you'll have a device that controls a boiler relay based on predicted presence, using PIR motion data and DHT22 readings. No more manual thermostat adjustments-just a smart, adaptive home helper.
What You'll Build
A wall-mounted panel that tracks room entry/exit over a week, stores patterns on a microSD card, displays current temperature and heating status on an OLED, and automatically switches a relay to control a heater or boiler. The system adapts to changing routines, ensuring warmth exactly when needed, and becomes more accurate as it learns daily habits.
What You'll Learn
- Programming ESP32 to interface with PIR and DHT22 sensors for reliable data collection
- Logging timestamps and temperature data to a microSD card and analysing occupancy patterns
- Using a DS3231 RTC for accurate schedule-based relay control
- Designing a safe 12V power supply with buck converter and enclosure for home use

Who This Kit Is For
Engineers and tech-savvy caregivers setting up home automation for elderly parents. Ideal for B.Tech ECE/EEE students developing assistive technology projects, participants of Smart India Hackathon focused on elderly wellness, and anyone attending ATL Tinkering Lab alumni workshops on IoT. If you are from IIT, NIT, VIT, BITS Pilani building a final-year project on smart homes, this kit provides a complete, pre-validated hardware set.
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?
Open the AI companion from the QR code for guided troubleshooting, or message us on WhatsApp for human support within 24 hours.
Can this system control a 230V AC boiler safely?
Yes, the 4-channel relay module is rated for 250V AC, 10A. When installed in the provided enclosure with proper wiring, it safely switches your boiler. Always consult a local electrician for high-voltage connections.
How long does the learning phase take?
The kit records occupancy for 7 days to build a baseline pattern. After that, it predicts heating needs based on time-of-day and temperature, automatically adjusting if routines change.
What if the elderly person is not tech-savvy?
The system operates automatically once installed. The OLED display shows room temperature and heater status at a glance, no interaction needed. You can monitor logs by swapping the microSD card periodically.
Elderly Care - Records occupancy patterns over a week and learns a heating schedule. Controls boiler relay based on prediction + DHT22.
