CairNet Anemometer Wind Speed and Direction Sensor


he device measures wind speed and direction and is powered by its integrated solar panel. It also has a rechargeable lithium battery (located under the ultrasonic plate).

The anemometer is compatible with all versions of Cairnet® (software update required), can be easily connected to it and can be mounted on the same support as the mini station.

Thanks to its low energy consumption, it offers a fully autonomous measurement solution that complements the environmental parameters (temperature, humidity and atmospheric pressure) offered by Cairnet.

Finally, the system has been specially designed for marine applications and guarantees robustness and reliability in all climatic conditions (humidity, corrosion, strong winds, etc.).
