Abstract
During the current COVID-19 epidemic, everyone needs to take measures, which include wearing a mask, keeping their distance, washing their hands, and avoiding touching anything unless it is absolutely necessary. They typically have a key housing and a key saddle to open ordinary doors. The body temperature sensor-equipped automatic door control system is a prototype designed to stop the spread of COVID-19, which is disseminated through droplets attached to traditional doorknobs, by minimising direct physical contact. In this paper, a temperature controlled door access system using Lab view and arduino is is proposed. LM35 connected to arduino is used for sensing the temperature. The software simulation of the system is done in Lab view, which is then interfaced with Arduino Uno. Further, the system consist of a relay and an LED to indicate whether the door access is granted or not. If a person’s body temperature is detected as a value within the normal body temperature range, then LED light appears and relay is activated. This results in opening of the door lock attached with the relay. If a person’s body temperature is sensed as a value greater than the normal body temperature range, then LED remains OFF . The system is designed to be placed outside institutions and malls where a person is allowed inside only if his/her body temperature is normal.
