1. A precipitation sensor comprising:

  • a cantilevered sensor member having a cantilevered portion and an upper and a lower surface extending on opposite sides of the cantilevered portion, the sensor member for receiving falling precipitation on the upper surface and vibrating when struck by such precipitation, the cantilevered portion having outer perimeter edges that are sloped downwardly for shedding the precipitation off the cantilevered portion;

    an electromechanical sensor incorporated with at least a part of the cantilevered portion of the sensor member for sensing vibrations of the sensor member caused by the precipitation, and generating an electrical response from which precipitation properties can be determined; and

    a support structure connected to the lower surface of the cantilevered portion at about a central region of the sensor member for supporting the sensor member, the cantilevered portion extending outwardly beyond the support structure.
