Contactless Human Body Temperature Measurement and Sanitization

Abstract

The design and working of Contactless Human Body Temperature and Sanitization is presented in this study. The system is intended to help prevent the spread of COVID-19 infection and assist in maintaining and/or improving community health and reducing the negative impact of the infection on the economy and society. We have used Proteus Design Suit & Arduino IDE software platform with simulating & programming the product algorithm and we are using Arduino Uno, MLX90614 sensor, Ultrasonic Sensors, IR Sensor , Buzzer and DC motor. The objectives of this work is to have a system consisting two sub-systems, the temperature sensor and the sanitizer sprayer, which is controlled from a common microcontroller and by design, can operate simultaneously. The design and development of the system go through the following methodology: System Specification, Literature Survey, Control System Design, Hardware Prototype Development, Results. Based on data obtained from tests made on the built prototype, a reiteration of the above steps is carried out where the control system (software logic) and parameters are adjusted so that they meet the specified performance for the system. The final test results are recorded and it does the temperature monitoring and on disinfecting the hands as expected. Photos of the Schematic and the prototype model ,and the flowchart on which the Arduino script is developed are shown. The non-contact sensor feature for both the recording of body temperature and the spraying of sanitizer provided by our model precludes the possible viral transmission from using traditional thermometers, readers handheld IR thermometer operators and avoids transmission between person to person.
