sensor reach the surrounding air temperature. The measurement is isplayed and is used for wind-chill
calculation.
Wind-chill Gives us information how cold it feels because of combined effect of current air
temperature and wind speed. The anemometer automatically calculates and isplays this subjective
temperature according to the latest formula.

seconds it displays two dashes.
Connection between sensor and display unit work on free 868 MHz band. Reach is up to 400 meters
when no obstacle is between sensor and display unit. Inside the building the range is much shorter.
