DEVELOPMENT OF IoТ-SYSTEM SOFTWARE ON ARDUINO HARDWARE PLATFORM

Abstract

The IoT market is growing rapidly and is in the billions of dollars. The Internet of Things covers all areas of human activity from smart small gadgets to smart cities, the concept of which is implemented at the state level. The Internet of Things, or «IoT», is the extension of the power of the Internet beyond computers and smartphones to a number of other things, processes, and environments. Over the past few years, IoT has become one of the most important technologies of the 21st century. With low-cost computing, cloud technology, big data, analytics and mobile technology, physical things can share and collect data with minimal human intervention. In this hyperconnected world, digital systems can record, monitor and regulate every interaction between connected things. The physical world corresponds to the digital world, and they cooperate. Given the ever-increasing number of connected devices, IoT continues its evolution by adding different layers to data that is already being exchanged and processed, and creating sophisticated algorithms that improve automation. And thanks to the variety of "things" that can be associated with it, IoT has made it possible to use a variety of applications for both individual users and entire industries. IoT in Ukraine is just at the beginning of the road and this opens space for the creation of various systems with different purposes and hardware. This article is devoted to an overview of the state of IoT in the world and Ukraine and a description of the developed IoT system using the Arduino hardware platform, the ThingsSpeak service and the interface using the Telegram bot. The system was tested with the implementation of a smart workplace with monitoring of air temperature, humidity, carbon dioxide, lighting brightness, atmospheric pressure, timely user notification of critical changes in microclimate to eliminate discomfort and improve human performance. Testing was also carried out after some refinement for the remote monitoring system of the carpenter's microclimate. Testing has shown that after a little refinement, the system can be used in various subject areas and is very economical.
