The ET-101BLE is a wireless, self-powered, Bluetooth enabled anemometer that can be used in fountain and water features, crane and construction, and nautical applications. Receive real time wind measurement data to your mobile phone via our free app (Etesian Wind).  This unit can also be paired with a Bluetooth receiver control display that provides control elements and data logging.

As with the ET-101, installing the ET-101BLE is simple and straight forward. Because the anemometer is wireless you won’t have the expense and effort of wiring the unit to the control display. An internal generator provides all necessary power and eliminates battery replacement maintenance that some anemometers require.
