Wind speed accuracy is +/- 3%. We guarantee every wind speed sensors is calibrated and tested before shipment.
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 (2400 mAh) can sustain the sensor for 4 years.
The transmission distance can reach as far as 400 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 WR-3 were paired and tested before shipping. If the text instruction is still not clear, please visit this video.
Yes. Users can connect unlimited numbers of receivers or combination of different types of receivers to one sensor (for example users can pair WR-3 sensors to WL-11 wireless wind logger).
Yes. We have bluetooth wireless anemometer for smartphoone (Android and iPhone) users. For more information, please visit our Smart Windy product page.
Third party certificate can be ordered on demand. The calibration certificate will be issued by SGS Lab.
