Monitor Your Baby’s Room Comfort with Arduino: Temperature, Humidity, Light Data Logger Kit

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

Build a reliable monitor that tracks the three comfort factors that matter most for an infant’s room: temperature, humidity, and light levels. Every minute, the Arduino reads the DHT22 and LDR, timestamps each reading with the DS3231 RTC, and writes it to a microSD card as a clean CSV file. Open it in Excel to visualise trends, spot discomfort patterns, or simply confirm the room stays perfect for your little one.

What You’ll Build

You’ll assemble a compact data logger that constantly samples the baby’s ambient environment. The device stores readings locally on a microSD card with no need for Wi-Fi or apps—just power it with a 9V battery and let it run. At any time, pop the card into a laptop, and you’ll have a spreadsheet with date-stamped columns for temperature (°C), humidity (%), and light intensity (LDR value). It’s a practical, hands-on project that mirrors the logic used in IoT nurseries and smart homes.

What You’ll Learn

• Wiring and reading a DHT22 digital temperature-humidity sensor through a single data pin
• Building light-sensing voltage dividers with LDRs and fixed resistors
• Configuring the DS3231 RTC over I2C for battery-backed accurate timekeeping
• Writing structured CSV data to a microSD module and managing file creation via SPI

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit sits perfectly with CBSE Class 11-12 students tackling sensor-based data logging assignments and B.Tech ECE/EEE undergraduates who need a reliable mini project for their first semesters. Smart India Hackathon participants will find the CSV-output structure easy to prototype with, while ATL Tinkering Labs can use it for workshops on environmental monitoring. Even hobbyist parents can build it to log nursery conditions without soldering or complex 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.
