Abstract
Stress analysis is an important parameter to understand the current status of one’s mental standing. So far, questionnaires and likers are the popular methods for collecting user data for subsequent analysis and conclusion extraction. The entire resulting of the usual process is based on the respondents’ answers. The subject’s mood, mental condition, and trustworthiness have a significant impact on the final result. The stress analysis in our work is based on biological concerns rather than mental behavioural considerations using the galvanic skin response (GSR). The GSR sensor is a one-of-a-kind skin resistance measurement sensor that procedures the electrical conductivity of human skin. Sympathetic activity is hugely variable in those who are stressed and increases sweat gland secretion, which leads to a further increase in skin conductance. The GSR sensor can be used to detect stress and other undesirable mental traits. Our proposed work blends an android application and microcontroller to decode skin conductance into a human-readable and visual form. The coordination of the Atmega 328 P microcontroller and BT-04 bluetooth provides the wireless display of readings in different ranges. Embedded C is used to programme the microcontroller, allowing easy modification and versatility. There have been several experiments to analyze stress using sensors and questionnaires but our system is based on practicality. It is portably usable even by a person who is not necessarily well familiar with the technology.
