Baby Room Comfort Monitor Kit v6 – Wireless Cry & Temperature Alert System with Arduino

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

Picture this: your baby sleeps peacefully in another room, and you’re immediately alerted the moment they cry or if the room temperature drifts outside a safe range—all thanks to a wireless monitor you built yourself. This kit transforms two Arduino Nanos into a long-range infant comfort monitoring system with real-time display and a buzzer alert at the parent unit.

What You'll Build

You’ll assemble a transmitter unit with a high-sensitivity microphone that detects cry events and a DHT22 sensor that continuously reads temperature and humidity. The receiver unit, placed anywhere in your home, shows live readings on a crisp OLED display and sounds an active buzzer the instant a cry is recognized or temperature crosses a threshold. The entire link runs on robust 2.4GHz communication, giving you a reliable, battery-powered baby alert system you can customize later.

What You'll Learn

• Configuring NRF24L01 modules for reliable 2.4GHz wireless communication between two Arduino Nanos
• Reading and calibrating a DHT22 temperature and humidity sensor for environmental monitoring
• Implementing sound threshold detection with the KY-038 microphone module to recognize infant cry patterns
• Integrating an OLED display and active buzzer for real-time alerts and status feedback
