Skin temperature monitoring with an instrument infrared sensors measuring based on direction and distance

Abstract

Skin temperature represents human body temperature. Measurement of body temperature aims to detect body organs changes activity, including fighting bacteria or viruses in the human body. Measurement of non-contact/long-distance body temperature is an important requirement during the Covid-19 pandemic. Based on this background, the development of long body temperature remote based on an Infrared Array SensorGrid-EYE sensor was conducted through microcontroller control. Variable of experiments to measure body temperature were distances and the inclined angle of the skin surface. The method of designing skin temperature monitoring glasses begins with three main stages process. The first process of understanding and analyzing the characteristics of solar cells, the process of measuring the energy of these solar cells. The second process involves designing and manufacturing electronic systems. The third process is by conducting an experimental experiment on temperature detector glasses. The components of this temperature detector system generally consist of infrared-based temperature sensors, signal conditioning circuits, microcontrollers, and were equipped with software that makes easy controlling. The results of the experiment showed the accurate measurement with a maximum distance up to 4 meters could monitor the skin temperature of human body with percentage error 0,18%. More than distance 4 meters, the ability of sensors was not accurately to monitor skin temperature of human body.
