Alat Pendeteksi Tingkat Stress Manusia dengan Sensor GSR Berbasis Mikrokontroler ATMEGA 328

Abstract

A stress detector has been designed in humans that is used to detect how high the level of saturation and human tension is by taking into account the parameters of skin conductivity and GSR (Galvanic Skin Resistance). This human stress detector that has been designed has a GSR sensor that functions as a detector of the skin conductance value of two fingers on one hand, ATMega328 is used because this microcontroller is easy to obtain and also very cheap in terms of the cost used. The ADC which is used to convert analog voltage to digital data is already in the microcontroller. The magnitude of the skin conductivity voltage and the GSR value will be displayed by the 16×2 LCD display. The GSR sensor will take data according to the parameters measured and then compare it with a table of limits on human stress levels for several people. From the results of the comparison with the table, it will be obtained a decision that displays the condition of stress levels in humans.
