Abstract :
This research paper presents a digital moving
av- erage filter for noise removal of the ultrasonic signal
which plays a major role in COVID-19 prevention
applications such as social distance detection systems and
sensor-based handwashing systems. The goal of the abovementioned filter is to improve the accuracy of distance
measurements. The filter design procedure was carried out
mainly using software called Matrix Labora-tory with the
assistance of hardware components such as the Arduino
development board, ultrasonic sensor, and breadboard.
Furthermore, a comprehensive analysis was conducted
between the original signal and the filtered signal to verify
the effectivenessof the filter.
