Baby Room Comfort Monitor Pro Kit — Arduino Uno Sensor System with Colour-Coded AQI Display

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

For parents who want to monitor their infant’s nursery beyond temperature and humidity, this kit combines an MQ-135 gas sensor, DHT22, and BMP280 to compute a unified Air Quality Index (AQI) that reflects potential irritants like ammonia, VOCs, and CO₂ levels. The colour-coded OLED screen shifts from green (safe) to red (unsafe) at a glance, giving you real-time peace of mind.

What You'll Build

You’ll assemble a desktop monitor that reads temperature, humidity, barometric pressure, and air quality, then processes the readings into a single composite AQI score. The OLED display shows the score with a colour background that immediately signals nursery conditions.

What You'll Learn

• Calibrate an MQ-135 gas sensor for indoor air quality measurements
• Interface DHT22 and BMP280 with Arduino Uno via I2C and digital pins
• Implement a weighted formula to compute composite AQI from multiple sensor values
• Program OLED display with colour-coded zones using Arduino libraries
