The Kimberly Clark Corporation, maker of Huggies disposable diapers, has confirmed that it is testing TweetPee, an iPhone app with a clip-on humidity sensor intended to capture when a child’s diaper is wet.

The company has announced that TweetPee is indeed real, and that Huggies Brazil is currently undergoing limited testing with hopes that the tests will expand with its' success.

Kimberly Clark spokespeople explain that a plastic humidity sensor activates the app, which then tweets parents that it’s time to change the diaper.  The company said the app would help parents track the volume of diapers they use, and when it’s time to reorder.

Neither the device nor the app is currently available for purchase, although KC marketing says it hope to begin testing in the US in 2014 and, if all goes well, have TweetPee on the market within four years.
