A new portable micro weather station

Abstract

We present a novel and practical micro weather station, which can sense temperature, relative humidity, pressure and anemometer, and is portable in small size and possesses high precisions. The micro weather station comprises multi-sensor chip, anemometer, measurement system, display system and power management system. Based on MEMS technology, multi-sensor chip integrated temperature, relative humidity and pressure is developed and manufactured. A drag force wind sensor using the torque of cantilever to measure the velocity of wind is developed. The wind direction can be measured by perpendicularly encapsulating the two wind sensor. Compared with those processes used in other types of micro weather station, the processes we used were very simple and compatible. All the results exhibit outstanding performances of our micro weather station. ©2010 IEEE.
