Description
Technical field
The present invention relates to intelligent diapers, and in particular to a kind of more induction points have the Intelligent urine of diaper saturation degree monitoring function
Cloth and its monitoring method.
Background technology
Since conventional diaper is replaced frequent, flushing dose is very big, slightly not note that the skin of baby be easy for being immersed in urine stain and
Just in stain, cleaning and drying condition are bad, easily grow bacterium.Disposable paper diaper are answered generation and are given birth to, and are increasingly subject to youth
Parent's likes.Many times, big people because carelessness or other reasons, can often forget about and change paper diaper to baby, these
Factor can all jeopardize the health of baby.Intelligentized paper diaper have more catered to the demand in market.
Existing intelligence diaper is used places a pair of induction electrode for having certain distance in induction region, is sensed by detecting
Whether the resistance value of electrode determines whether defecation in the range of given threshold, and principle is similar to Raindrop sensor.Induction electrode electricity
Change in resistance means the humidity variation of electrode environment, so it is directly using humidity sensor to have another Humidity Detection mode
