Long gone are the days of peeking at a diaper to determine if it's that time or not. You know what I'm talking about. Introducing the Electronic Diaper: a high-tech interior garment for infants with a sensor that monitors your child's 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. In theory, it works by making use of a voltage divider which is extremely sensitive to wetness at the tip of the probe. When wet, electricity flows across the leads of the probe but with some resistance. The voltage drop is measured through the microcontroller's analog to digital converter every second. As soon as any voltage is detected, a buzzer goes off like a siren followed by chirps at 5 second intervals for as long as wetness is detected. The LED turns on and stays light indefinitely, however, at the onset of wetness. So after a diaper change, a reset is required.
