Specifications-Wind Speed And Direction Sensor
The wireless module used on wind speed sensors only requires very low power consumption. The transmission power consumes 20-30 uA in normal condition and 35 mA peak current in every 2 seconds. The standard 3.6V Lithium battery can sustain the sensor for up to 3 years.
The transmission distance can reach as far as 500 meter in open space. The actual distance depends on the topology & obstacles. According to user experiences, the vertical transmission distance can be 200 meters in height. Harmonic disturbances are possible in theory, but so far we did not receive complaints about this.
Pairing between sensor & receiver is based on address.
The address is labeled on the sensor body. User can set receiver address by setting menus. All WL-21 were paired and tested before shipping. If the text instruction is still not clear, please visit this video.
Yes. Users can connect unlimited receivers to one wireless sensor.
Manufacturer and third party (issued by SGS) Lab certificates can be ordered on demand.

What Our Clients Say
The Scarlet wireless anemometer WL-21 is the best wind speed meter I ever used in my career life. It makes my job much easier and I can monitor wind speed in my office under bad weather conditions.
I have been using WL-21 on all the lifts in my company for the last 6 months and couldn’t be happier with their performances and high quality.
We are quite happy with the Scarlet WL-21 wireless wind speed meter. It works perfectly in our workshops. I highly recommend this wireless anemometer.
