Design and Implementation of a Smart Baby Crib

摘要

Many people are so busy that they face additional difficulties with everyday life. Parents in particular may have many responsibilities, yet babies and infants continue to need special care. This paper proposes a smart baby crib to help both parents and baby in several ways by providing numerous services in two modes, manual and automatic. In manual mode, the user can control the crib's swing and start music playing wirelessly using an application installed on a smart phone. In automatic mode, the crib starts swinging automatically when the baby cries, and swings continuously until the baby stops crying alongside playing music to make a baby be quit and sleep. In addition, if the motion and music do not calm the baby, the crib messages the designated parent's mobile phone using Global System for Mobile communication (GSM) technology to seek immediate attendance. The system is implemented using a microcontroller, a D.C motor, a sound transducer, an h-bridge, and a rechargeable battery, and this has been tested in real time environments. Experimental results show its efficiency and simplicity.
