Agriculture is becoming one of the most important sectors of the world economy. Smart technologies help the agro sector to enter confidently the digital era and optimize processes qualitatively. This will ensure efficient use of natural resources. The use of the IoT (Internet of Things) system will increase agricultural productivity, improve quality, increase crop yields, as well as it will ensure food security. The use of sensors in agriculture is an important step in creating an intellectual farm. They provide a realtime data on condition of objects in tens of square kilometres, particularly, the parameters of humidity, temperature, vegetation, and light intensity. This paper discusses four different ways of a remote cultivation process of plants (flowers) in agriculture. Plants were grown in different pots and in different locations to determine the air temperature, humidity, soil moisture, and light intensity in view to predict the plants’ growth. The Arduino microcontroller was used for the sensor system, plant growth was monitored by means of the sensors and the Arduino.
