A sensor for measuring flow direction and airspeed is disclosed that is suitable, because of its small size, for rapid instrumentation of research airplanes. A propeller driven sphere rotating at a speed proportional to airspeed presents a reflective target to an electro-optical system. The duty cycle of the resulting electrical output is proportional to yaw angle and the frequency is proportional to airspeed.
