AUTOMATIC E-BABY CRADLE SWING BASED ON BABY CRY

AUTOMATIC E-BABY CRADLE SWING BASED ON                                 BABY CRY.

My latest Arduino DIY project is Automatic E-Baby Cradle Swing based on Baby Cry.

Parents in the present world are busy in their professional life, so they do not get sufficient time to take care of their babies. It may be expensive for the household to afford a nanny.

Today’s woman has to manage home along with their office work simultaneously. After long working hours, they have to take care of the home along with the baby. They may not get enough time to swing the cradle manually and sooth the baby. Moreover, in today’s life style, it is very difficult even for the housewives to sit nearby their infants and sooth them whenever they cry. Enhancing sleep quality is an important research topic, as quality sleep is important for everyone, especially for infants . A comfortable electric cradle with a low power consumption that can letinfants fall asleep quickly is desired by many parents and numerous novel inventions based on swing mechanisms in the form of springs or rods have been developed .Hospitals have neonatal and maternity units. Nurses in these units have to take care of baby and sooth them whenever they cry. 

The system is designed to help parents and nurses in infants care. The design aims at following points: 

1.  Cradle starts swinging automatically when baby cry and swings till the baby stops crying. 

Sends message to mother’s mobile when  baby cries for more than a stipulated time indicating that baby needs attention.
