The Smart Water Flow Sensor project is our solution aimed at addressing the issue of water waste in households by effectively monitoring water usage in the building's pipes. To provide users with convenient access to the water consumption data, the project incorporates an LCD screen that displays the information in near real-time. Additionally, a dedicated port in the local network's router has been assigned to allow users to easily monitor their daily water consumption and current water flow in real-time. Our project uses several interconnected components, including a water flow sensor, Arduino Uno microcontroller, ESP8266 transceiver, a custom 3D printed enclosure, and a custom power supply. The most notable accomplishments are our custom PCB designs for the power supply and main board, in addition to the Wi-Fi connectivity that allows for wireless communication. Some areas of improvement would be increasing wireless accessibility to allow the owner of the system to connect from any network and access the data stored.
