A Cost Efficient Contactless IoT based Body Temperature Detection System

Abstract

In the recent outbreak of Covid-19 pandemic, various methods has been adopted to prevent and control the wide spread of pandemic. One of the commonly used method is by detecting the body temperature. This is to isolate those obtained higher body temperature who are possibly infected with the virus. Body temperature detection device is commonly deployed at the entrance of merchants for this purpose. However if one person is detected in one merchant with higher body temperature, this information is not bundled with his/her identity information. Therefore his/her entranced to other merchants are not linked and warned, and causing a possible spread of pandemic ifother customers who appeared in the same premises arenot beingnotified. Inthis work, an IoT based body temperaturedetection system is developed. In this system, the body temperature data is obtained and sent to the internet cloud together with the identity information of that person. This allow easy tracking of the potentialvirus infected person.The collected data can befurther analysed using online analysis tool. Furthermore, the identityinformation is obtained using QR code which eliminate the ordinary procedure of writing personal data into logbook. The QR code method is contactless and able to avoid the infection of virus through the contact of pen and logbook. This system is developed with low-cost material and is affordable for small merchants.
