Wind Speed & Direction Meter
with a clever touch
Published in issue 332, May 2004
This ingeniously designed circuit may be just the ticket for those interested in weather observations, in particular, wind speed and direction. The clever bit about the instrument is that both wind speed and wind direction are measured with a single sensor: a rotational speed meter with three blades, one fitted with a small vane. One advantage of the specific design of the combined sensor is that the mechanical construction of the anemometer is far simpler than that of traditional meters while also reducing the risk of wear and tear as well as breakdowns. The instrument readout showing wind speed and direction is on an LCD as well as via a serial output that allows a PC or an (NMEA compatible) navigation instrument to be connected.
