Baby Room Comfort Monitor Kit with Arduino Nano + HC-05
Arduino Nano Baby Room Comfort Monitor with Phone Configuration Over Bluetooth
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Create a nursery monitor that not only shows temperature and humidity on an OLED screen but also lets you tweak comfort settings wirelessly from your phone. The Arduino Nano stores your thresholds in EEPROM, so a power cut doesn’t erase them—ideal for Indian homes where uninterrupted care matters.
What You'll Build
You’ll assemble a compact device housed in an ABS enclosure that reads DHT22 sensor data, displays it live on a 0.96in OLED, and can switch a 5V relay (for a small fan or heater) based on thresholds. All configurations are sent over HC-05 Bluetooth without needing to recompile code, and they survive every restart.
What You'll Learn
- How to integrate a DHT22 with Arduino Nano and output real-time readings to an OLED display.
- Setting up HC-05 Bluetooth for wireless parameter updates from a smartphone.
- Writing and reading configuration values to Arduino’s internal EEPROM for persistence.
- Controlling mains-rated appliances safely using a 5V relay module.

Who This Kit Is For
Designed for CBSE Class 11-12 students exploring embedded projects, B.Tech ECE/EEE undergraduates, or ATL Tinkering Lab tinkerers. Even a tech-savvy parent can build this for their own nursery and avoid commercial monitors that lack local configurability.
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?
Scan the QR code on the box to open the AI companion, which has wiring diagrams and troubleshooting steps specific to this kit. WhatsApp support is also available.
Do I need to write the smartphone app myself?
No. The kit includes a ready-to-install APK that communicates over Bluetooth, so you can set thresholds without any app coding. The Arduino sketch is fully commented for customisation.
Will a power cut reset all my settings?
No. The configuration is saved in the Arduino Nano’s EEPROM, which retains data even when the battery is removed or power fails.
Can I extend the monitor with more sensors?
Absolutely. The prototype board and detailed schematic make it straightforward to add extra modules like a PIR motion sensor or an ESP8266 for WiFi logging later.
Infant Care — Nano saves configuration to EEPROM over BLE from phone. Settings persist power cycles. Compact OTA config.
