ABSTRACT:
Early detection and warning of wetness in a diaper leads to an early change of diapers, keeping the infant dry and healthy. This invention monitors the diaper for dryness by sensing the conductance between two terminals in contact with the diaper. The device aids in toilet training the infant by learning wetting patterns and providing early warning. The device promotes the efficient use of diapers and reduces the cost of using diapers.
