Baby Room Comfort Monitor Kit with Arduino Uno + HC-05
Baby Room Comfort Monitor Kit — Check Nursery Temperature from Your Phone with Arduino Uno & HC-05
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Worried about your baby's room temperature while they sleep? This kit lets you build a compact Bluetooth monitor that reads temperature and humidity from the DHT22 sensor and sends it to your phone every 2 seconds. With Arduino Uno and HC-05, you’ll have a custom, real-time comfort guardian without ever disturbing your little one.
What You'll Build
A wireless baby room comfort monitor that continuously measures temperature and humidity using the DHT22 sensor and transmits the data via HC-05 Bluetooth module to a free Serial Bluetooth Terminal app on your smartphone. The readings update every two seconds, so you’ll always know if the nursery is getting too warm or too dry. You’ll assemble the circuit on a breadboard and can power it with a 9V battery for portable placement.
What You'll Learn
- Wiring and reading a DHT22 digital temperature/humidity sensor with Arduino
- Pairing and configuring the HC-05 Bluetooth module for wireless serial communication
- Using a Serial Bluetooth Terminal app to receive live sensor data on your phone
- Building a complete stand-alone environmental monitoring system on a breadboard

Who This Kit Is For
This beginner-friendly kit is perfect for CBSE Class 11-12 students exploring wireless communication, ATL Tinkering Labs building sensor-based projects, and B.Tech ECE/EEE students prototyping simple IoT devices. It is also a great first electronics project for new parents who want a practical, phone-connected monitor they assembled themselves.
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?
Our AI build companion, trained on this exact project, is just a QR scan away—and it walks you through every step. If you need a human, reach us on WhatsApp and we'll help you debug.
Do I need to download any app?
Yes, you’ll need a free Serial Bluetooth Terminal app, available on Android and iOS. The build guide will show you exactly how to configure it to receive the temperature and humidity data from your monitor.
Can I monitor the baby's room from another floor?
The HC-
Infant Care — HC-05 sends DHT22 readings to Serial Bluetooth Terminal app on phone every 2 seconds.
