This article discusses issues related to the concept of the Internet of Things and its application to the development of the Smart City. Smart City or "Smart City" is a new concept for the introduction of technologies (information and communication) to manage the life of the modern city. Existing technologies for long-distance data transmission in the Internet of Things are analyzed. Based on the calculations, the justification of the efficiency of LORA technology is substantiated, the energy potential of the communication line for LORA technology is given, the capacity of the LoRa network is determined. The network architecture has the best relationship between increasing the battery life of IoT devices and providing communication range. The protocol operates in a non-licensed range, and this is its uniqueness in cost and speed of implementation. Based on the study of the experience of implementing the protocol in the city of Lviv, the advantages and problems of implementation were identified. The possibility of using the technology in large cities was assessed. Software has been developed that allows the user to check that everything in his house is in order and that there are no gas leaks, water leaks and no movement in the house. The practical use of IoT in the "Smart City", the use of LoRaWAN technology, the principle of the network are shown. The experience of using the LoRaWAN protocol in Ukraine has been studied and analyzed. The experience of cities on the introduction of Internet of Things technologies in the housing system is considered.

This article analyzes existing supplements that help people monitor their health and nutrition, and reveals important current issues that have received little attention so far. Eating disorders also include some developmental abnormalities that can be prevented by diet, disorders that respond to dietary treatment, food allergies and intolerances, potential food hazards, and the interaction of food and nutrients with medications. This web application is for people who have special diets due to illness, doctors' recommendations. The implementation involves analyzing the possibilities of developing a software system that allows you to track meals, give advice on diet planning and recommend recipes and products for the user's health indicators to be adjusted. Potential users of this software product will be primarily patients with eating disorders, but also those who simply need to change their diet for one reason or another, such as allergies, diabetics, etc. To control their diet, you can use a variety of tools that differ from each other in the degree of convenience and accessibility. The easiest way to control is to independently count the food eaten and record information about them. Today, there are many applications, both mobile and web applications, that are designed to monitor diet, pick up recipes or keep a diary of meals. The health nutrition web application is designed primarily to monitor your health and the fullness of all the necessary components of the food you eat, as recommended by your doctor. The essence of the application is that the user enters his basic data such as gender, age, height, weight, and optionally, for more accurate and useful recommendations, the presence of allergies, the presence of diseases or genetic predisposition to them, food preferences, increased / reduced test results (which may be affected by nutrition), recommendations of doctors, etc.
