IoT Non-contact Body Temperature Measurement System Implementing Access Control for COVID-19

Abstract:

The need to have total control over body temperature within COVID-19 crisis has made infrared sensors a valid alternative to traditional thermometers, so to avoid direct contact and thus virus spreading. In this work, an IoT system is presented which performs access control to popular places through the integration of body temperature, humidity, ambient temperature and servomotor sensors. Data captured by the sensors network is transmitted via Bluetooth Low Energy to a server programmed into a raspberry, which in turn is devoted to send data to a web platform for real time monitoring. Experimental results are discussed, by revealing a 0.42% average relative error as compared to standard contact thermometer. The proposed compact and low-cost IoT platform is able to provide thermographic detection in a fast and accurate way, thus avoiding contagion risk.
