An introduction for WET DIAPER DETECTOR..

Normally nurses, parents and patient guardian have problem in detecting wet diapers. The Wet Diaper Detector is a device that is used to detect the wetness of a diaper. It will triggered through NE555 to give output via buzzer and L.E.D at the same time. From here, the guardians will alert to the presence of wetness in a baby diapers or undergarments.

We select the circuit project first before we choose the name of our project. This is because our project is basically not in the given catalouge of projects, and we have made several changes before deciding our final project due to circuit malfunction during its testing phase with our supervisor.

Figure 1.0 The idea comes from our supervisor. 

Thanks to Sir Mohd Zubir.

Wet Diaper Detector is a device for infants with a sensor that monitors child's and eldest comfort level.  It provides instant audible feedback by way of a buzzer as well as a persistent optical sensory notification system by way of an  LED. 

It works by the use of wetness condition the diaper which is located at the tip of the probe. When the diaper is wet, current flow across  the leads at the probe.

As soon as any voltage is detected, a buzzer goes off as long as wetness is detected,   LED turns on and stays light indefinitely, however, at the onset of wetness.  So after a diaper change, a reset is required.
