ParkingMap uses ultrasound technology to connect each parking space in indoor and covered car parks. The sensors are installed in the ceiling above the aisle. They point towards the space at a 45 degree angle and detect parked cars.
The ultrasound sensors use a multicoloured LED to provide visual information on the availability of each parking space. Red indicates that it is occupied and green indicates that it is available. Several colours are available to personalise the message.
