I know exactly what you mean, Chuck. One crying child is stressful enough without the phone ringing, something beeping or anything else that demands your immediate attention. When my daughter was a baby, she wore diapers that had a yellow line on them. That line changed color when her diaper was wet. As the months went by, I started to be able to tell when he diaper was dirty, simply by looking at it.
So let me get this straight: you plug the moisture sensor into your phone, run the pee app, stick the sensor in the diaper and put the phone... where? Are diapers going to have a phone holster? Does my infant need a data plan for this? If my kid pees a lot, am I going to run the risk of going over my data plan limits?
Honestly though, I can see this concept being useful in hospital/daycare situations as others have suggested, but to need a phone for this is just a solution in search of a problem. There ought to be far simpler solutions that don't require connectivity to the internet and would cost considerably less. I think a simple mesh network with a centralized data collection system would be cheaper, simpler, and less expensive.
Well, it's a little creepy, but is it any creepier than executing a "crotch grab" on a toddler to check if the diaper is wet? Before I had kids, the first time I saw a parent execute that move on a three-year-old, it kind of freaked me out a little. Then I had kids of my own and realized it's actually a really practical way to check for wetness. If done well, this sensor (basically just a bluetooth moisture sensor, I think) could be helpful, since in my experience the kid won't cry until long after the diaper is wet (after it starts to get cold or skin irritation begins). Seriously, they seem to not be bothered at all by a wet diaper. I guess it's the warmth. By the time they cry, a rash has already set in, and I recall having to check early and often. And getting peed on a few times. For some reason kids find that extremely funny.
