An electronic diaper includes a diaper, a sensor a controller, an LED lamp or a horn. The sensor senses dampness of a diaper and give a signal to the controller, which has a control circuit for calculating and converting the signal and gives out a warning signal to the LED lamp or the horn to give out light or sound for indicating that the diaper has become wet and needs to be replaced with a new one. And a timer may be further added to show the time of wetting of the diaper.
