An aerodynamic device is provided for detection of physical conditions of wind turbine blade operation. One or more vibration sensors are mounted on the blades in an aerodynamic housing and configured to monitor a physical condition of the blades that varies in accordance with a vibration of the housing. A processor is operably coupled to the one or more vibration sensors. The processor may be configured to use the vibration frequency of a component of the blade to determine the physical condition of the blade, and generate a signal indicating the physical condition of the blade when determined.
