Abstract
This paper aims to investigate the issues encountered in the fabrication of a wind speed sensor, specifically the bouncing phenomenon of the optical interrupter sensor. Due to the mechanical structure of the switch, oscillations continue to occur after opening and closing, which is known as the bouncing phenomenon. This paper explores the use of hardware or software to debounce, making the return values of the sensor more accurate. Finally, software debouncing is used, employing delay in the coding process to avoid the occurrence of the bouncing phenomenon, resulting in more precise readings.
