The “Smart” Diaper Moisture Detection System
Haj Ali, Rana
A diaper or a nappy is a type of clothes that allows the person to urinate or defecate without the use of a bathroom , by absorbing liquids, as a result, the surrounding environment will not be polluted. This report presents a design of smart diaper using Bluetooth module , which comprise of wet sensor "soil moisture" , Arduino Uno, and application on smart phone . The sensor is placed in the area most vulnerable to moisture. The wetting of the diaper decreases the resistance between two terminals, which are connected with conductors. As a result, terminals resistance fall down below the predefine resistance value and Bluetooth module send the data reading from sensor to the Smartphone application .
