Abstract
Since December 2019, the COVID-19 pandemic is currently anticipated as one of the greatest global threats to public health, well-being, global economic and social stability. Temperature screening is significant as it may identify people who have an elevated temperature, which is one of the symptoms of COVID-19. Proper hand hygiene and wearing a face mask are also adequate hygienic preventives to obstruct the spread of a viral infection. Therefore, this project aims to evolve a smart system with temperature screening, hand sanitizing, face mask detection and data profiling. Hardware was first designed using SolidWorks combined with software which is Arduino and Python programming language. The prototype was 3D printed and constructed using corrugated board. The system was controlled by Arduino Uno. Performance evaluation for each stage of smart system had been carried out to analyse the performance statistically. Temperature measurement is accurate with deviation error ±0.2'C for distance variation 0cm to 12cm and ±0.6C for distance variation 12cm to 20cm respectively. The hand sanitizer dispenser takes average 1.95s for pump out the hand sanitizer. At low liquid level, liquid level detector sensor give notification where red LED lights up. In addition, face mask detection has an average accuracy of 94%. Temperature measured was tabulated through PuTTY into file. Thus, temperature screening using a rack and pinion mechanism, automatic hand sanitizing, face mask detection through CNN and data profiling were successfully developed. Hence, this smart system able to assist for screening and monitoring for improvement of COVID-19.
