Based on the research of Parking Guidance System (PGS)
Based On Real Time Operating System (RTOS), it can be
concluded that this parking guidance system can be
implemented well in UBINUS Anggrek Campus’ parking
building without worrying any interference that might occur
and sensors can measure well in a distance of 10 – 280 cm. By
implementing RTOS FreeRTOS to PIC32, sensor controller
can control three ultrasonic sensors reliably. Besides that, the
average time for master controller (PC) to update data from
sensor controllers is 1045 ms from the scale of 133 – 2600 ms.
