ABSTRACT
Covid-19 is an infectious disease that was first discovered in Malaysia on 24 January 2020. It has become the main issues globally and infected many people around the world. Physical-distancing is a practice that is suggested by the World Health Organization to limit the spread of Covid-19 by keeping distance of at least 1 meter from each other. There are many seats installed in public places such as schools and hospitals as well as public transport like buses and flights. It is very useful and good if the seats able to give alarm so that the users always practicing physical distance. This study presents a development of miniature prototype that will give alarm to public chair user if the physical distancing is not followed. The system is built using STM32F446RE ARM microcontroller to control the operation of alert device, push-buttons as the weight sensors, 7-segment displays to inform the status of the device and a buzzer to give alarm sound. Findings show that the system is working accordingly and able to remind its users to keep physical distancing thus helping against the spread of Covid-19. © 2021 IEEE.
