SMART Baby Crib #openfab #eyuboglu

Moms can relax with the smart baby bed!

1. Arduino UNO
2. Buzzer
3. OLED display
4. Humidity sensor
5. Blue and red LED light

This project is an Arduino-based smart baby crib system designed to improve babies’ comfort and alert parents in possible situations. It provides a simple yet effective prototype that helps parents monitor their baby’s comfort remotely. In future versions, features such as mobile notifications, temperature monitoring, or an automatic drying system can be integrated. #thankstoopenfab #openfab #eyuboglu #eyubogluegitim #eyubogluegitimkurumları #ozyeginuniversity #eyuboglu.k12.tr
