Abstract
An apparatus is provided for use with capacitive presence detection systems. The apparatus includes a sensor (10) in the form of a tape which may be adhesively affixed to an object such as a parking gate (4) arm. Additionally, spaces for use in mounting the sensors (40) are disclosed which increase the depth of field of the sensor. The tape is a sandwich having a plastic film top layer, a metallic foil middle layer, and a plastic bottom layer having an adhesive material.
