Smart Diaper: Non-stop Diaper Monitoring System

This paper presents the development of a smart diaper system by applying the Internet of things (IoT) concept. The smart diaper system has a wet sensor known as the wet detector unit. The central controlling unit of the wet detection system is the low-cost wireless micro-controller. The micro-controller creates a bridge between the cloud (IoT cloud) and the wet detection system. A mobile application has been developed for the convenience of end-users. All sensors data collected from Smart Diaper are presented in apps through the cloud. The wet detector sensor is placed between the inner layers of a diaper. When the wet sensor sensed any wet, it knocked the micro-controller to transmit the value to the cloud. The mobile apps pushed a notification based on the wet value. Thus the user revived a message from the system and performed the diaper change operation.
