An ultrasonic and temperature sensor prototype using fuzzy method for guiding blind people

Abstract

A blind person must be protected from direct contact with unknown high-temperature objects in the surrounding environment. A system is needed to be able to detect the location and temperature of objects without direct contact. Ultrasonic sensors are used as object distance detectors and infrared temperature sensors are used as object temperature detectors without any direct contact. This system is processed with ATMega328 and information is conveyed to the user via buzzer sound signals and DC motor vibrations. The system as a whole is planted in a glove designed specifically to facilitate the user in using the tool.
