Wireless Baby Monitor with Temperature and Cry Alert – Arduino Nano Kit

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

Parents and caregivers want reliable, always-on monitoring of a baby’s room without expensive proprietary gadgets. With this kit, you assemble a dual‑unit system – one node placed in the nursery senses sound levels and room temperature, the other stays with the parent and displays data while sounding an alert for crying. The NRF24L01 radio link keeps the two Arduinos in sync, giving you a flexible, customizable monitor that puts engineering into your own hands.

What You'll Build

A transmitter unit powered by an Arduino Nano reads the DHT22 for temperature and humidity and monitors the KY‑038 microphone for sharp sound spikes. When cry‑like noise is detected, a flag is sent wirelessly to a receiver unit. The receiver also gets real‑time temperature data, shows it on a crisp 0.96‑inch OLED screen, and triggers an active buzzer to alert you. The entire system fits on a breadboard, letting you modify thresholds, display layouts, or add logging later.

What You'll Learn

• Establishing reliable wireless communication between two Arduino boards using NRF24L01 transceivers
• Interfacing the DHT22 digital temperature/humidity sensor and parsing its serial data
• Processing analog sound input from the KY‑038 to distinguish cry events from background noise
• Integrating a 0.96‑inch OLED display and active buzzer into a complete alert system

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit fits CBSE Class 11–12 students designing physics or electronics projects that involve sensor integration and wireless data transfer. It’s an ideal mini‑project for B.Tech ECE/EEE first‑year students, Smart India Hackathon prototypes, and ATL Tinkering Lab makers who want to build a practical baby monitor that demonstrates real‑world embedded systems. Hobbyists at IIT, NIT, VIT, and BITS will also enjoy customizing the code and packaging for personal use.

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.
