Wireless networks wind sensor based on micro wind velocity chip and electronic compass

In this paper a kind of wireless networks wind sensor, based on micro wind velocity chip and electronic compass, is introduced. The micro wind velocity chip, which is fabricated with MEMS technology, is designed based on drag force and thermal principle. When the output of micro wind velocity chip is max value, the wind sensor obtains wind velocity and direction by measuring the value of micro wind velocity chip and electronic compass. Moreover, the package of wireless networks wind sensor is designed. By adopting rotation structure, the wind sensor package is especially suitable to use in weather monitoring WSN.
