Resumen
In this paper, we propose a new design of smart faucet system that measures the body?s temperature prior the water falling in pipes by using DS18B20 sensor an act correspondingly. The design was implemented using Arduino Uno Microcontroller that is connected with temperature senor to control two water valves (i.e. Hot & Cold) in order to mix the proper amount of hot and cold water conforming the body temperature. The proposed design can be easily adapted to the water piping system of already constructed buildings by replacing the old faucets with the new automated ones. Such design can be very useful to reduce the amount of wasted water during the setup phase of mixing hot and cold water.
