Background. The article is devoted to the research and development of a level sensor for an innovative bottle designed to systematically monitor the hydration level of the human body. An analysis of the demand for existing solutions in the smart bottle market shows that the devices in question do not have the function of identifying the contents, as a result of which the accuracy of measurements and forecasts regarding the user's health indicators may decrease. Materials and methods. As part of the research work, an option is proposed to eliminate this disadvantage through the introduction of an intelligent level gauge with a visual readout into the bottle design, which ensures high measurement accuracy regardless of the physical properties of the liquid. The article covers the classification and analysis of level sensors in the framework of solving the problem of designing a "smart" bottle, determining the key functions of the device being developed, describing the design and principle of operation of the synthesized version of the level gauge. Results and conclusions. The proposed approach to the implementation of an intelligent bottle creates prospects for the organization of an effective hydration monitoring system, opening up new opportunities in the field of health care and improving the quality of daily life.
