Abstract

A method for indicating and alarming about wet level of a diaper involves using a humidity sensor to perform relative humidity detection on the diaper, when the detected relative humidity is below 50% rh˜60% rh, showing the diaper's wet level as 0% rh, and when the detected relative humidity is 85% rh˜95% rh or more, showing the diaper's wet level as 100% rh, wherein functional conversion is performed to convert the relative humidity ranging between 60% rh and 85% rh˜95% rh proportionally into the diaper's wet level between 0% rh and 100% rh.
