A frame with a long supporting beam has an upright mast at one end. A cable and pivot hold another beam at a low angle to the ground. The far end of the pivoting beam has a weight attached, and arrows indicate that the pivoting beam can swing from side to side. A vane descending from the pivoting beam is bracketed by magnets, and another magnetic attached to the pivoting beam moves over a sensor attached to supporting beam. A cable runs from the sensor to a nearby box containing small electronics boards.
