Abstract

See full text

A method includes transmitting a measurement command from a controller to an occupancy sensor with an address that corresponds to an occupancy sensor identifier. The measurement command causes the occupancy sensor to transmit an ultrasonic signal into a parking space, receive echo signals reflected back to the occupancy sensor, and determine, based on the echo signals, whether the associated parking space is occupied or empty. The method includes subsequently sending a status check to the occupancy sensor and receiving a response that includes the occupancy sensor's determination as to whether the associated parking space is occupied or empty. The method also includes calibrating the occupancy sensors from the controller.
