I don’t know how many people actually care about the water temperature at home, but if by some odd reason you are one of those persons, the Faucet Buddy is here to help you out.

Sadly, it seems like it is only a concept so far, but it has the potential to go into the mass-production mode. Basically, you just need to attach the Faucet Buddy into a sink fixture, and the temperature is displayed on the small screen by the red LED lights.
