The rapid growth of the Internet of Things (IoT) has significantly transformed the healthcare sector by enabling real-time monitoring, automation, and intelligent decision-making systems. One of the emerging applications of IoT in healthcare is smart infant monitoring, which aims to ensure the safety, health, and comfort of babies, especially in situations where continuous human supervision is not possible. This paper presents the design and development of a Smart Nanny Device, an advanced IoT-based system that provides comprehensive monitoring of an infant’s physiological and environmental conditions in real time.

The proposed system integrates multiple sensors, including temperature and humidity sensors to monitor environmental conditions, sound sensors for detecting crying patterns, and motion sensors to track the baby’s movement.

Additionally, a camera module is incorporated to provide live video streaming, enabling parents or caregivers to visually monitor the infant remotely through a mobile application. The system continuously collects and transmits data to a cloud-based platform, where it is processed and analyzed to detect any abnormal conditions or potential risks.
