Baby Room Comfort Monitor Kit — Animated Weather Display with Arduino Uno, DHT22 & BMP280

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

A tiny chest rises and falls under a gentle sun icon — the baby’s room is exactly 26°C, with 55% humidity and stable pressure. You built that reassurance yourself, without writing a single line of code from scratch. This kit turns an Arduino Uno, a DHT22, a BMP280 and a 1.8-inch TFT into a visual infant comfort monitor that animates sun, cloud or rain icons based on real-time sensor readings, helping parents and caregivers keep nursery conditions just right.

What You'll Build

A breadboard-based environmental display that reads temperature and humidity from the DHT22 and barometric pressure from the BMP280, then draws animated weather icons on the ST7735 TFT. The display switches dynamically: a smiling sun when conditions are comfortable, a drifting cloud if humidity rises, and raindrops if temperature or pressure trends suggest discomfort. The final build includes a sturdy 9V battery snap, making it portable enough to place near the crib or on a shelf.

What You'll Learn

• Interface two I2C sensors (DHT22 and BMP280) on a single Arduino Uno and merge their data streams
• Program pixel-level graphics on an SPI-driven ST7735 TFT, including custom animated icons
• Translate sensor thresholds into visual logic — temperature, humidity and pressure combinations drive distinct display states
• Work with pull-up resistors and decoupling capacitors to stabilise sensor readings on a breadboard

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Ideal for CBSE Class 11–12 students building a practical sensor dashboard as a school project, or for ATL Tinkering Lab entries that need a tangible health-tech prototype. B.Tech ECE/EEE first-year students will find it a solid introduction to multi-sensor data fusion and SPI displays. Even participants preparing for the Smart India Hackathon can use this as a rapid environmental monitoring module. The intermediate level assumes you have uploaded a blink sketch before — we handle the sensor libraries and animation code.

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.
