Parking lot vacancy monitoring module includes infrared sensors and Zigbee modules which are interfaced with PIC Microcontroller. Vacancy monitoring module detects the presence of vehicle in the parking areas and provides the status to the users in real time. Reservation module includes GSM modem which is interfaced with a coordinator system. The user can book their parking spots through SMS.
