No cables to string, no batteries to change - ever!
Measuring wind speed (and temperature) has never been easier
 Etesian Technologies breeze is the world's first selfpowered
and wireless anemometer. All the expense and
hassle of wiring is eliminated. Damage to your logger or
controls from lightning is eliminated. The internal
generator provides all necessary power. Never a battery
to replace.
• "Industry Standard #40 Cups"
• Data transmissions start at 2 m/s (5 MPH)
• Up to 500 feet line of sight transmission
• Temperature probe incorporated into sensor and
its measurement is wireless as well
