About anemometer
Introduce
Anemometer is a device used for measuring wind speed.
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.
Features
- Power: 5V~30V DC
- Communication: pulse output
- Resolution: 0.0875m/s
- Accuracy: ±（0.2+0.03V）m/s
- Measuring range: 0~70m/s
- Working environment: -20℃~60℃，0%RH~80%RH
Size
Circuit
- PNP OUTPUT
- NPNR OUTPUT(RL=5.1K)
Connector
Anemometer has a special connector that has four wires of different colors.

Basic usage
- Prepare an Arduino UNO to connect the anemometer, the connection as the blew figure.
| Arduino UNO | Anemometer |
| 5V | VCC |
| GND | GND |
| D2 | OUTPUT |
- 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.
- Verify and upload it to the board.
- Open the serial monitor window, you will view the measured wind speed.
