 ## About this project
 
-A smart system that will measure the water temperature through a digital temperature sensor and alter the water temperature according to the user's requirements.
+A smart system that will contain two sensors. The first one will measure the temperature of the water and the second sensor will measure the quality of the water. For instance, it will measure if the water is purified enough to be drinkable. All the necessary information will be displayed on the user's screen using Bluetooth.
 
 ## Design & Architecture
 ------------------------------------------------------------------------
 
-In order to accomplish the smart water heater, the project will be in steps. The first step includes the smart water temperature sensor. It will measure the temperature and it will indicate it on the screen. The second step will be the smart water heater where the temperature will rise and the temperature sensor will measure the new temperature.
+In order to accomplish the smart water system, the project will be in steps. The first step includes the smart water temperature sensor and analog turbidity sensor. The information will be displayed on an Android application.
