People who live in a home furnished with bathtub sometimes thinks of taking a bath at their home. But, every time they fill up their tub, the user constantly checks the temperature of the water with their hands. Wetting their hands all the time. What if you have a sensor that tells you what exact temperature is? If so, all you have to do is to turn the knob as you want the temperature to be. Keep yourself dry until the last moment you jump into your tub!
