No Batteries - No Wires
Measuring Wind Speed and Direction Has Never Been Easier
 Etesian Technologies breeze is the world's first self-powered
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
• Integrated direction sensor - both signals
wireless
