Baby Room Comfort Wireless Alert System: Build with Arduino Nano + DHT22

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

Every parent worries about their baby’s room temperature, especially during India’s harsh summers or sudden winter chills. This kit lets you build a reliable wireless monitor that instantly alerts you if conditions stray outside the safe range for your infant — so you can focus on being a parent, not a thermostat watcher. Using two Arduino Nanos and a pair of NRF24L01 transceivers, you’ll create a system that transmits live DHT22 sensor readings to a display unit near you.

What You'll Build

You’ll assemble a two-node system: a battery-powered transmitter in the baby’s room that reads temperature and humidity with the DHT22, and a receiver unit near you that shows real-time data on a crisp 0.96-inch OLED screen. If the temperature drops below 20°C or rises above 26°C, the receiver’s active buzzer sounds a loud alert, so you can adjust the room’s fan, heater, or AC immediately. The whole build fits on breadboards and requires no soldering.

What You'll Learn

• Wiring and programming the DHT22 digital temperature/humidity sensor
• Setting up NRF24L01 2.4GHz wireless communication between two Arduino Nanos
• Displaying live sensor data on a 0.96-inch OLED using I2C protocol
• Implementing threshold-based alert logic and controlling an active buzzer

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Parents and makers who want a hands‑on way to monitor an infant’s sleep environment. Students in CBSE Class 11‑12 science fairs or ATL Tinkering Labs will find it an ideal project for IoT and healthcare themes. B.Tech ECE/EEE beginners learning wireless sensor networks (WSN) can use it as a working prototype, and Smart India Hackathon participants can extend it with data logging or mobile alerts. Adult supervision is recommended for builders under 12.
