Development of Heat Detector Based on Fuzzy Logic Using Arduino Board Microcontroller

Abstract

Heat detectors are the best ones for detecting flame fires. Unlike other types of fire detectors, heat detectors can be used in polluted and aggressive environments. They are resistant to various interferences. However, heat detectors have the highest operation inertia. You can reduce the fires detection time by heat detectors using fuzzy logic mathematical apparatus. The heat detector based on fuzzy logic was developed and investigated in this article. For this purpose, a microcontroller based on the Arduino hardware was used. Heat detector responds to both fixed temperature and the speed of temperature rise. A new model of heat detector based on fuzzy zero-order Sugeno logic with two inputs in the MATLAB/Simulink package was developed. Research of the accuracy and adequacy of the obtained mode was done. In the course of research, it showed 100% accuracy and adequacy in relation to the developed model in the Fuzzy Logic Toolbox. In the Arduino software package, using the C programming language and the Arduino Mega 2560 board, a hardware implementation of the Sugeno zero-order fuzzy logic heat detector was implemented. Experimental studies have been carried out. The error of the result calculated by the Arduino did not exceed 2.5%. Execution time of one complete cycle of fuzzy block is 0.004 sec.
