Abstract: The Internet of Things (IoT) has the potential to transform the ways we live in the world; we have more-efficientindustries, more connected cars, and smarter cities, all these as components of an integrated IoT system. The current number of working mothers has greatly increased. Subsequently, baby care has become a daily challenge for many families. Thus, most parents send their babies to their grand- parents’ house or to baby care houses. However, the parents cannot continuously monitor their babies’ conditions either in normal or abnormal situations. This paper proposes a “Smart Baby Cradle” through the use of IOT technology will help parents to keep eye on baby’s motion, temperature and moisture. Cradle is an appliance which uses to carry a baby and oscillate for comfort sleep of a baby. It takes a lot of effortsfrom parents to physically rock the cradle to keep eye on baby and to generate swinging motion of the cradle. When baby is kept inside the cradle need to be constant monitoring parent to keep tracking of baby’s activity. He proposed idea in thisprototype of smart cradle will allow the cradle to efficiently integrate itself with a smartphone typically android device.ESP32 microcontroller will be used to assemble all the sensors and hardware component required. Constant monitoring of the baby inside the cradle will be done. If any activity such as urination or baby waking up from sleep or baby cry occurs a notification through an SMS will be sent to the parent’s device. The Smart cradle will also have additional features such as rocking the baby automatically via geared motor mechanism. The cradle is suitable for parents who are not able to invest all their time at home sitting near the baby. Other applications of this cradle can be at a maternity hospital as an assistant to the staff who are responsible to lookafter the baby.Keyword: ESP32, Microphone, Ultrasonic Sensor, Servomotor, PIR Sensor, Cloud Computing
