    This paper describes the industrial realization of a solid-state wind sensor, that is one without moving parts. The sensor's key component is a heated silicon chip that is nonuniformly cooled by the wind. The resulting flow-induced temperature gradient in the chip is measured by integrated thermopiles. Their output is digitized and processed by a microprocessor in order to determine wind speed and... View full abstract»
