Autonomous Smart Baby Cradle with Raspberry PI and Internet of Things

Abstract

In this society, men and women are work hard to maintain their social status. The caring for their babies is very important. This paper deals with the design and implementation of the smart baby cradle system. The main objective of this paper is to design an IoT based baby cradle in a monitoring system that helps the parents know their babies' status. The guardian has to take care of their child until they were asleep. DHT22 sensor is continuously monitoring the temperature and humidity of a baby and these values will be automatically uploaded on the ThingSpeak cloud. USB camera is used to monitor the position of the baby. While the baby is sleeping on the cradle and if the baby starts crying the sound sensor module detects the baby's crying sound and so that a servo motor turns ON and starts swinging the cradle. In the conventional system, if a baby cries, the guardian of the baby comes and swings the cradle. In this paper, when the sound sensor detects the crying of a baby then the cradle will be automatically swinging. This is implemented by the servo motor operated with a particular angle. Sensor values are uploaded to the cloud using Thingspeaks.
