About anemometer


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 which reflects the wind speed more accurately. Besides, this anemometer is totally Waterproof, with a stable installation design, suitable for outdoor applications.

In working, if the anemometer turns one round in one second, the transmitter will output 20 pulses, which means the wind speed is 1.75m/s.

  • 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: NPNR
  • Working environment: -20℃~60℃,0%RH~80%RH

Connector Mark Definition
Brown line VCC Power supply
Black line GND Grounding
Green line (PNP)OUTPUT Pulse output
Blue line (NPNR)OUTPUT Pulse output

Note: PNP OUTPUT is the inverse pulse of NPNR output.

Basic usage

  • Prepare an Arduino UNO to connect the anemometer, the connection as the blew figure.

  • Use the cable to connect the Arduino UNO to the PC.
  • Get the program demo from the Github, and open it by Arduino IDE.
  • Select the development board and port.
