The absence of information regarding the availability of parking spaces in public
places is an obstacle for vehicle owners, especially now most of parking systems
are used only rely on information comes from visual observations of officers on
guard. Therefore, there is a need for a smart parking system based on the Internet
of Things (loT) that can monitor the availability of the latest parking spaces and
also reserve parking spaces through an application on their smartphone. RFID is
used to identify vehicles which entering and leaving the parking area and an
infrared sensor is implanted in each parking space to detect if the parking space is
in use, then the data will be processed by an ESP32 microcontroller and stored in
the Realtime Database then uploaded to the Android application as information of
the availability parking space to the user before heading to the parking area.
