Baby Room Comfort Monitor Kit with Arduino Uno + Sensor
Arduino Baby Room Comfort Monitor Kit — Wireless Temperature & Humidity for Your Nursery
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 crying baby often signals a room that’s too hot or too cold. With this kit, you’ll build your own wireless comfort monitor that streams live temperature and humidity readings to your phone every second—helping you keep the nursery safe and cosy through every nap, without tiptoeing in to check a thermometer.
What You'll Build
A compact, battery-powered sensor station on a breadboard that pairs an Arduino Uno with a DHT11 temperature-humidity sensor and an HC-05 Bluetooth module. Once assembled, it automatically sends real-time data to the Serial Bluetooth Terminal app on your smartphone. Place it discreetly in the nursery and monitor the room from your couch or kitchen—no Wi-Fi or cloud account required.
What You'll Learn
- How to interface a DHT11 digital sensor with Arduino and read calibrated temperature and humidity values.
- How to configure an HC-05 Bluetooth module as a wireless serial link for long-lasting data streaming.
- How to write Arduino code that continuously samples and transmits sensor data every second.
- How to use a smartphone terminal app to receive and visualise live data from a microcontroller project.

Who This Kit Is For
This kit is designed for CBSE Class 5-8 students preparing a science or IoT exhibition, ATL Tinkering Lab explorers diving into wireless sensor projects, and parent-makers who want a practical, baby-safe gadget for the nursery. B.Tech ECE students prototyping Bluetooth-based health monitoring systems will also find it a handy reference.
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.
What if I get stuck during the build?
Simply scan the QR code on the box to access the AI companion, which has been trained on this exact project. You can also reach us on WhatsApp for human support if you need it.
Can I monitor my baby's room from another floor?
The HC-05 module provides a typical Bluetooth range of up to 10 metres indoors. For across-the-house monitoring, you can later upgrade to a Wi-Fi module (like ESP8266) using the same sensors.
Does the Serial Bluetooth Terminal app work on iPhone?
The standard app on the Play Store is Android-only, but iOS users can use any BLE Terminal app that supports HM-10 or similar modules. Our AI companion includes setup notes for iPhone users.
Is the DHT11 accurate enough for a nursery?
The DHT11 offers ±2°C temperature and ±5% humidity accuracy, which is sufficient for checking that the room stays within the recommended 20-24°C range. For higher precision, you can swap in a DHT22 (not included).
Infant Care — HC-05 sends live DHT11 temperature and humidity readings to Serial Bluetooth Terminal app every second.
