Development of temperature monitoring system with thermal sensors and microcontrollers.

Abstract

Covid-19 epidemic Affects the way of life of the general public Preventing the spread of COVID-19 therefore it is urgent One popular measure is temperature monitoring, the purpose of which is to measure the temperature of several people and provide an audible alarm. Can measure normal temperature and over temperature At present, most temperature measurements are measured with a thermometer, which normally has a temperature camera and a temperature sound alarm. which use different equipment In this research, a temperature monitoring system was developed using a thermal camera with a sound alarm in case the temperature exceeds the standard value. This system consists of a microcontroller connected to a thermal camera and an MP3 playback module. The experiments were divided into four experiments: (1) the system accuracy test; The aim of this experiment was to determine the accuracy of the device by comparing the temperature measured by the developed device with the temperature measured with a thermometer. The results showed that the mean temperature difference was 0.23 degrees Celsius. (2) The system efficiency was investigated. This is an experiment to find fault with the system. By having the tester use his hand to measure the temperature 10 times, the results showed that the system was able to measure all 10 times, representing 100%. This experiment was to determine the distance between the device and the tester. The tester had to stand 50, 100, and 150 cm from the device. The results showed that all three distances were measured. And when the temperature exceeds 37.5 degrees Celsius, it was found that the system could work 10 times, representing 100%. The results of the development of the system showed that the developed device can measure temperature either by using your hands or standing away from the device.
