Baby Monitoring System using Arduino Uno

India is one of the countries in this world, having the highest number of birth rates but with such high birth rates, the number of women, working, after giving birth is no less but has increased to a great extent. When a mother has given birth to a newborn, she usually spends more than a year attending to the baby's needs. During this time, if she must leave for her work, it makes it difficult for her as she must leave her baby in good hands. To address this problem, this research proposes a solution in the form of a smart baby monitoring system. The research focuses on developing and implementing this technology to make it easier for mothers to keep an eye on their babies remotely. We aim to build an automatic baby monitoring system in which the environment of the baby is monitored by getting the temperature and humidity values also maintaining the environment by switching of the fan to the required amount to maintain the temperature. If the baby cries, the parents are alarmed by ringing a buzzer which could be placed in their room. The cradle is made to automatically swing to help the baby fall asleep, whenever it makes noise. The system also involves a web application being created which is updated from time to time, about the status of the baby (- asleep or awake) and the environment of the baby. In the near future, we also plan to integrate a Camera module with our system and display the video on our website so that the parents not only get to know the status of the baby, but also be able to see their baby.
