Baby Room Comfort Monitor Kit v5 — Build an Arduino Data Logger for Your Infant's Room

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

Your baby’s room environment matters — sudden changes in temperature or humidity can disrupt sleep and comfort. With this Baby Room Comfort Monitor Kit, you’ll assemble a compact Arduino data logger that quietly captures temperature, humidity, and light levels every 15 minutes, storing them to EEPROM so you can later review patterns via a simple serial download. No Wi-Fi, no cloud — just reliable, offline environmental tracking that puts you in control.

What You'll Build

You’ll build a standalone monitor that sits in your infant’s room, logging three critical comfort parameters: temperature (accurate to ±0.5°C with the DHT22), relative humidity, and ambient light intensity. The data is timestamped by a DS3231 real-time clock and saved to the Arduino’s internal EEPROM — enough to store over 500 readings. Once connected to a computer via USB, you can download the entire log as a CSV-like serial output to analyze with a spreadsheet or custom script.

What You'll Learn

• Wiring a digital temperature/humidity sensor (DHT22) on a breadboard
• Reading analog light levels with an LDR and voltage divider
• Using the DS3231 RTC module to add accurate timestamps to data
• Storing and retrieving sensor data from Arduino’s EEPROM memory
