摘要：
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 non-uniformly 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 direction. For wind speeds between 0.1 and 25m/s, the errors in the computed wind speed and direction are less than 0-5m/s (or +/-3%) and +/-3degrees respectively.
