Baby Room Comfort Monitor Kit v3
Baby Room Comfort Monitor Kit v3 – ESP32-Powered Ozone & UV Tracker for Infant Safety
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Bring laboratory-grade environmental vigilance into the nursery. You’ll assemble a self-contained monitor that uses ML8511 UV sensors corrected for altitude by the BMP280 to derive a continuous proxy for Dobson unit ozone levels — giving you a data-backed view of the UV and ozone conditions your infant breathes, without needing a satellite or meteorological station.
What You'll Build
A weatherproof, solar-rechargeable monitoring node that logs dual UV-A/UV-B readings, temperature, humidity, and altitude to a microSD card while displaying real-time ozone proxy values on a 1.8-inch TFT. Position it near the baby’s window or outdoor play area to track how local ozone levels change with sunlight and weather, helping you time safe indoor air moments.
What You'll Learn
- Calibrate dual ML8511 UV sensors for UV-A and UV-B differential measurement
- Implement BMP280-based altitude correction for accurate UV irradiance normalization
- Compute a running ozone proxy (Dobson unit estimate) using sensor fusion logic
- Design off-grid power with an LM2596 buck converter, 18650 cells, and a solar panel

Who This Kit Is For
Designed for engineers, research-oriented parents, and B.Tech/M.Tech students tackling environmental IoT or child health devices. Ideal for Smart India Hackathon challenges on air quality, ATL Tinkering Lab mentors who need advanced demonstration rigs, and final-year projects at IIT, NIT, VIT, or BITS that demand sensor fusion and data logging.
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 using the QR code inside. It walks you through each wiring diagram and code module. If you need a human, reach us on WhatsApp; our engineers reply within one business day.
How does the ozone proxy actually work?
The algorithm normalizes UV readings by altitude (from BMP280), then applies a lookup table derived from atmospheric attenuation models to estimate total column ozone in Dobson units. The companion explains the math step by step.
Can I log data without Wi‑Fi?
Absolutely. The on‑board microSD module stores all timestamped readings using the DS3231 RTC. You can retrieve logs later or add Wi‑Fi uploads as an extension.
Is this suitable for a nursery with a newborn?
The waterproof enclosure and secure mounting keep electronics out of reach. The sensor provides environmental awareness only, not a medical alert. Many parents use it to understand daily UV/ozone patterns and plan outdoor time accordingly.
Infant Care — ML8511 UV-A and UV-B sensors with BMP280 altitude correction compute a proxy Dobson unit ozone estimate over time.
