Smart sensor devices for water dispensers, water dispensers using these smart sensor devices, and a system for monitoring and analyzing drinking water usage for water dispensers.

Abstract

The invention relates to a smart sensor device (100) for a water supply machine (200), a water supply machine (200) using this smart sensor device, and a drinking water use monitoring and analysis system (300) for a water supply machine (200). The smart sensor device (100) comprises a device housing (101), a proximity sensor (102), a central processing unit (103), a memory (104), a data exchange medium (105), and a power supply unit (106). The central processing unit (103) is configured to self-learn the type of water container that has not been learned by recording data during the use of the water container, constructing a depletion curve, creating container shape characteristic data (Container Fingerprint), and storing this data in memory (104). When the next water container is used with the water supply machine (200), the central processing unit (103) extracts the characteristic data of this water container, compares it with the stored characteristic data to determine whether the water container is of the same type as the learned water container.If a match is found, the stored characteristic data is used to determine the remaining water capacity and is updated based on usage data from similar water containers; if there is no match, the device repeats the learning process. This allows the device to adapt to various types of water containers and improve accuracy over time.
