Plus produit

The CV7SF2 is ultrasonic wind sensor solar wireless designed for day-boats, cruise sailing boats, club houses, sport grounds, parks, local weather stations.

The major improvement of this product is that it could work under daylight and night time. The ultrasonic wind sensor solar wireless CV7SF2 is endowed wind measurement frequency about 16 Hz. By calculation, it could have a data refresh about 2 Hz frequency.

The ultrasonic wind sensor solar wireless CV7SF2 is provided with a battery last technology, type of LiFePo4. The main feature is that the battery can be charged or discharged lots of time. Moreover, the battery is compatible with high temparatures, that we can see at the top of the mats. On the other hand, the battery is interchangeable.

Furthermore, a barometer has been added on this product.
