Anemometer with NPN Pulse Output
An anemometer is a device used for measuring wind speed and is a common weather station instrument. After testing many anemometers in the market, we found out this NPN pulse output anemometer quality is good while cost-effective.
Unlike the analog output version anemometer, this anemometer output pulse reflects the wind speed more accurately. There a detailed usage guide for Arduino learners on how to check the pulse and calculate the wind speed. Besides, this anemometer is totally Waterproof, with a stable installation design, suitable for outdoor applications.
