When the urine is detected, the light alarm device and the sound alarm device start alarming. After the reset switch is pressed down, the light alarm device and the sound alarm device stop alarming, and the urine alarm starts the next urine wetting detection. The multifunctional urine reporter is also provided with a power switch.

The sensing device comprises a probe and a voltage comparator, wherein the probe is electrically connected with the voltage comparator, and the voltage comparator is electrically connected with the microcontroller. The on-off state of the probe is monitored by a voltage comparator, which in this embodiment is LM 339.
