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.
