1. A sensor module for monitoring wind speed and direction at a first location along a power corridor through which a high voltage electrical conductor extends, and for detecting wind-induced aeolian vibrations of said conductor said module comprising:

  • (a) housing means mountable to said conductor at said first location;

    (b) a support member mounted on said housing means having a vertical axis;

    (c) a plurality of discreet piezo-electric elements, each of which generates an electrical signal proportional to pressure exerted thereon, arranged in seperate segments about said vertical axis upon said support member, whereby each of said segments has a surface facing in a seperate, known, horizontal direction and generates an electrical signal having a value proportional to pressure exerted thereon by wind blowing from the direction in which the element faces;

    (d) said housing means, support member and piezo-electric elements each having a configuration suitable for avoiding corona effects from said conductor;

    (e) signal processing means for receiving said electrical signal values from each of said elements and selecting the highest of said values;

    (f) means for detecting wind-induced aeolian vibrations of said conductor and for generating a further electrical signal having a value commensurate with the frequency of said vibrations; and

    (g) signal transmitting means for transmitting to a second location, remote from said first location, RF signals indicative of said highest value and the one of said elements generating said highest value, thereby providing an indication of the wind speed and direction and of the frequency of said aeolian vibrations at said first location.
