Abstract
In accordance with one embodiment of the present disclosure, a sensor system includes a sensing surface and an array of pressure sensors arranged on the sensing surface. The array of pressure sensors includes at least one pressure sensor is parallel to the sensing surface, at least one pressure sensor is angled between parallel and perpendicular to the sensing surface, and at least one pressure sensor is perpendicular to the sensing surface. The pressure sensors are micro electro mechanical system (MEMS) barometric pressure sensors.
