Baby Monitoring System by using Arduino Uno

Abstract

This paper presents the design and implementation of smart baby cradle system, a new low-cost baby monitoring system with multiple automatic functions. The system allows the cradle to swing automatically when baby cries. It has a cry analysis system which detects crying voices using sound sensor and automatically swings the cradle till the baby stops crying or zero voice detection. The system also has built-in fan that switched on when an increase in surrounding temperature is detected by DHT11 sensor. If the cradle is to be used manually, the speed of the cradle can be controlled as per the user need. Arduino Uno module is utilized in managing all the connected electronics components. This system aids parents and caretakers to look after the babies without high-demand physical attention.
