Baby Room Comfort Monitor Kit
Baby Room Comfort Monitor Kit: Automatic Louvers with Arduino & BH1750
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Ensuring a baby's comfort means shielding them from harsh midday sun and welcoming fresh morning air. With this kit, you’ll build a four‑panel motorised louver system that automatically opens at sunrise and closes at sunset—hands‑free climate control for the nursery. Perfect for engineering students and mechatronics hobbyists, the project brings together precise light sensing, reliable real‑time scheduling, and synchronised servo movement in a smart‑home prototype you can deploy in a real infant room.
What You'll Build
You’ll assemble a weather screen driven by an Arduino Uno, where a BH1750 lux sensor reads ambient light and a DS3231 RTC supplies drift‑free time. Four SG90 micro servos rotate the louvers, while a DHT22 temperature/humidity probe and an OLED display create a dashboard of nursery conditions. The result is a self‑operating unit that tracks natural daylight, keeps the room cool, and prevents over‑ventilation after sunset—no baby monitor app required.
What You'll Learn
- Interfacing a BH1750 I2C lux sensor and translating ambient light readings into servo angles
- RTC‑based scheduling: using DS3231 with Arduino to trigger events at precise times without drift
- Controlling multiple SG90 servos in sync to motorise physical louvers
- Integrating a DHT22 temperature/humidity sensor with an OLED display for environmental monitoring

Who This Kit Is For
This advanced kit is built for B.Tech ECE/EEE students working on IoT/embedded systems projects, participants in the Smart India Hackathon developing smart nursery solutions, and makers from IIT/NIT/VIT who want a hands‑on mechatronics build. ATL tinkering lab mentors will also find it a powerful demonstration of sensor‑actuator integration for higher‑secondary students.
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.

Can I adjust the open/close schedule for my baby's nap routine?
Yes, the RTC schedule is fully programmable. The Arduino code lets you set custom sunrise and sunset windows—the AI companion will walk you through changing the opening hour and lux threshold.
Will the louvers still work on cloudy mornings?
The BH1750 measures exact lux, so you define a threshold. If light stays below that value, the louvers remain shut. The RTC acts as a backup clock to prevent the system from opening too early or staying open past sunset.
What if a servo jams? Is there a safety feature?
The SG90 servos include internal stall‑current protection, and our sample code adds a soft‑stop limit to avoid over‑rotation. The included PCB prototype boards also make mechanical mounting more secure.
