ABSTRACT:
An improved bedwetting detection device is responsive to moisture in the bed of the user to create an alarm when bedwetting occurs. The device includes controlling circuitry connected to metallic conductors (12, 14) installed in the bed of the user. The circuitry periodically provides electrical pulses to the conductors (12, 14) so as to minimize the introduction of electrical impulses into the bed of the user. Furthermore, the pulse created by the circuitry is of a very low voltage so as to further minimize the amount of electrical energy introduced into the bed of the user.
