The growing popularity of nanosensors in various automotive applications requires new methods for counting the frequency of electrical signals, into which the measured non-electrical parameters are converted. This need is because automobile nanosensors are to register very small changes in the measured parameters that, besides, can change very fast. The paper proposes for use in automotive nanosensors a frequency calculation method based on the principle of rational approximation, which meets the above requirements.

Problem. IoT is a technology that is becoming a part of different branches of our life, including healthcare. Currently, some hospitals and other health care facilities in developed countries al-ready use IoT systems for remote monitoring of patients' health. However, most of these systems are expensive, rather complex and are intended for use exclusively by medical staff. All this causes the fact that the mentioned systems remain inaccessible for mass application, and con-stant control over patients is still carried out by the direct presence of doctors, nurses, etc. At the same time, such continuous observation of the patient also requires quite high financial costs and time. Moreover, some people, e.g. elderly people or people with chronic diseases do not have an opportunity to be constantly under medical care. The purpose of this work is improving the speed and quality of a patient’s medical care by monitoring their condition periodically and by rapid remote informing other people about the health state. Method. The IoT-based system to monitor the parameters of a patient’s health periodically and send the information to the medi-cal staff or patient’s relatives online is offered. The requirements for the system are defined and its architecture is proposed. It consists of an Arduino board, the set of sensors, Internet and GSM modules and the IoT analytics platform. The main health state parameters to be monitored and the corresponding hardware for monitoring the parameters of the patient's state are deter-mined. Results. The prototype of the IoT-based system to monitor a patient’s heart rate and send the information through a Cloud IoT platform to the medical staff or the patient’s relatives is developed. The results of the experiment on measuring the pulse of 12 people and sending the data to the Cloud showed the efficiency of the system. Conclusions. The developed system can be used either in hospitals or at home. The main advantages of the system are low price, usability, compactness and flexibility in measuring a patient’s state parameters. The prospects for further research are connected with equipping the system with a GSM module to send the SMS when any of the parameters have abnormal values and to respond the users’ requests about the pa-tient state.
