Abstract

• The commercial hand-held contactless thermometers are used to measure the body temperature to detect the virus-infected persons within a distance of about 3 feet. It is not a sufficient distance for virus protection without personal protective equipment (PPE) suit. The web server based on the contactless infra-red (IR) thermometer can measure the body temperature and display it on the PC monitor or mobile phone at the distance of 150 feet indoor and 300 feet outdoor from the sensor module. Since ESP8266 MCU is the Wi-Fi chip with microcontroller capability, it is suitable to use in the hardware interfacing and software development of a web server based contactless IR thermometer. Web server-client communication takes place by using the Hypertext Transfer Protocol (HTTP). Web server home page is created by using Hypertext Markup Language (HTML) and Cascading Style Sheet (CSS). Since asynchronous Javascript and XML (AJAX) are used in a web server system, the real time-temperature readings are automatically updated without the requirement to refresh the web server home page.
