Abstract:
A portable hand-held vane anemometer that can determine wind speed, temperature, wind chill and humidity, comprising:a casing that encloses a microprocessor that is adaptable to determine wind speed, wind chill, air temperature and humidity;a temperature probe that is coupled to the casing and that is external to the casing, the temperature probe being in electrical communication with the microprocessor, so that the microprocessor can determine the temperature of the air;a humidity sensor that is coupled to the casing and that is external to the casing, the humidity sensor being in electrical communication with the microprocessor, so that the microprocessor can determine humidity; andan impeller and a magnet mounted on a rotatable shaft, such that wind causes rotation of the impeller, the magnet and the shaft, said rotation of the magnet producing an electrical signal that is proportional to the wind speed, and the electrical signal being receivable by said microprocessor, so that the microprocessor can calculate the wind speed in response to the electrical signal and the wind chill in response to the electrical signal and the temperature probe.
