This is my fifth-semester project on the topic of domestic water supply and how to raise awareness. This project aims to visualize water consumption in a transparent, understandable manner. Water meter is found in every home but adapted to the specific needs of the supplier. With this project, I wanted to account the needs of both, the suppliers and the consumer.
The smart water meter is digital and measures the consumption digitally via a hall effect sensor. The data is stored on a small server transmitting it via wireless LAN to various devices. Other sensors, e.g. in the toilet or washing machine can add data to achieve full transparency. Energy harvesting is powering the Meter and server with a small dynamo. This dynamo converts the water pressure (potential energy) into electric energy. A rechargeable battery provides a stable power supply in case of high current load or extended absence. Therefore, the water meter can be operated independently and without additional infrastructure.
