Peace-of-Mind Baby Room Temperature Alert Kit Using Arduino Nano + DHT22 Wireless System

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

Nothing matters more than a baby's safety, and this kit puts accurate, real-time temperature monitoring right in your hands. You'll build a dual-node wireless system: a battery-powered sensor sits in the nursery, while the parent unit records data on an OLED and sounds a buzzer the moment temperature drifts outside the 22–26°C comfort zone. Within one afternoon, you create a reliable alert system that removes guesswork and gives you the freedom to rest easy.

What You'll Build

You'll assemble a transmitter module that reads room temperature every few seconds with a DHT22, then sends the data wirelessly via NRF24L01 to a receiver. The receiver displays the live temperature on a crisp 0.96-inch OLED and triggers a loud active buzzer if the room crosses the safe threshold. The entire system runs on independent 9V batteries, so no cables trail near the crib and the parent unit can sit wherever you are.

What You'll Learn

• Wireless data transmission between two Arduino Nano boards using NRF24L01 modules
• Interfacing a DHT22 sensor and reading temperature with high accuracy
• Programming visual alerts on a 0.96-inch OLED display
• Designing a battery-operated embedded system with proper decoupling and power management

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Parents who want a practical, code-and-circuit introduction to wireless sensing will find this kit immediately useful at home. CBSE Class 11-12 physics students can explore data communication and IoT fundamentals during project work. B.Tech ECE/EEE students often use a similar setup in Smart India Hackathon demos, while ATL Tinkering Labs and IIT/NIT/VIT/BITS students gain hands-on experience with real-world sensor networking.

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.
