Description:

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 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.

Features:

• Power: 5V~30V DC
• Communication: pulse output
• Resolution: 0.0875 m/s (that is, if 20 pulse detected in 1s, the wind speed is 1.75 m/s, and 3.5m/s if 40 pulse detected)
• Accuracy: ±(0.2+0.03V)m/s
• Measuring range: 0~70m/s
• Output: NPN
• Working environment: -20℃~60℃，0%RH~80%RH

Package List:

• 1 x Anemometer with NPN Pulse Output
