In this paper, the authors present a design of smart diaper wet detector using wireless and computer, which consists of wet sensor, wet detector unit, RF transceiver, GSM alarm system and computer. A wet diaper detector comprises an elongated pair of spaced fine conductors which form the wet sensor. The sensor is positioned between the layers of a diaper in a region subject to wetness. When the diaper is wet, the resistance between the spaced fine conductors falls below a pre-established value, the wet detector being operative.
