A compact anemometer, capable of detecting the magnitude and

direction of the wind in a plane, is presented. The device constitutes an

evolution of a class of sensors that exploit a recently proposed original

approach, involving fluidic processing of the pressures induced around a

cylinder. A significant size reduction with respect to previous prototypes has

been achieved by the use of a tiny differential pressure sensor based on a

MEMS System on a Chip. Preliminary characterization performed in a wind

tunnel is presented.
