Аннотация: (English) Inventions in the Field of Contactless Control and Monitoring of Drinking Water and Cow's Milk Quality in the Ecosystem and Infrastructure of a Smart Home. Introduction. The quality of drinking water and milk in the infrastructure of a smart home essentially determines the quality of life. In all methods of quality control for water and milk, conductivity is commonly considered a clear indicator of purity. The more contaminants there are in water or milk, the lower its electrical resistance, and the cleaner the water or milk, the higher its electrical resistance. This was acceptable for a long time, until international terrorism reached its current level of proliferation, and until overall environmental pollution reached unprecedented scales and dimensions, as it is today. Purpose. These are certainly not all the factors that justify the urgent need for more comprehensive quality control of water or milk, but they are very important ones. Almost all existing technologies, devices, and equipment for monitoring the quality of water or milk have a very narrow range of technical capabilities and do not cover all the parameters that need to be constantly monitored. This is necessary to ensure that water or milk, which, due to the aforementioned reasons, is contaminated to the extent that it poses a danger to human life and health, does not reach the consumer.
