Smart Water - Temperature and Quality of Water Controller

---

IoT Project for the course "Internet of Things" during the winter semester 2021-22

About this project

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 according to the turbidity measures. 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 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.
