Graphical visualization of data measurement of programmable microcontroller according to ARDUINO-project example

In this paper, it is presented the Arduino Uno single board microcontroller based system, which measures air condition parameters, and also the developed software for graphical visualization of the measurement results. The results and working principles of some type of Arduino boards are analyzed. The developed software for Arduino data parameter visualization is described. An experimental prototype is produced. The DHT-11 sensors for temperature and moisture measurements, as well as the WSP1110 Nitrogen Dioxide NO2 sensors are used in the project. Software for Arduino measurement parameter graphical visualization is developed by using Java, Javascript, Jquery, Html, Css, PhP programming languages. The software execution and the main requirements for the running of this project are analyzed. It was written a software code for Arduino IDE (Sketch), which controls temperature, moisture and Nitrogen Dioxide NO2 sensors.
