Ultra-Low-Power Ultrasonic wind meter.

Wind meter, a 45m/s IoT, Ultra-Low Power Ultrasonic Anemometer:

     Ultra-Low-Power (RS485 NMEA 0183: 0,25 mA @5V, 1Hz / MODBUS : 1 mA @5V, 1Hz)

     Ultra-Low-Power (UART): 0,15 mA @5V, 1Hz 

    Small: 70x70 mm 

     Light: 130-240gr


The ULP represents an important technology breakthrough condensing an extensive R+D investment that brings us to a new generation of ultrasonic wind meters. 

  • Both shape and firmware have been enhanced for an improved rain performance, being this point key for static applications such as weather stations. 

  • Mechanical design has been revamped making the unit more robust and dependable. 

  • We feel very proud to release a unit that requires under 0,25mA @1Hz (RS485), and 0,15mA @1Hz (UART)

  (Further protocols under request).

NMEA 2000 output

The Ultra-Low-Power Ultrasonic wind meter can output an NMEA 2000 signal when using an NMEA Connect Plus NCP_W2000 model.

Add an NMEA Connect Plus :


  • NCP_ HighEnd : Receives wind data from any ULTRASONIC wind meter within Calypso´s range of products. Converts NMEA 0183 wind sentences and/or Bluetooth signal into NMEA 0183 network and Bluetooth. It can also be used as range-extender using it as a Bluetooth-repeater.

  • NCP_ W2000 : Connects your Ultra-Low Power ULTRASONIC wind data to NMEA 2000 network. Allows the connection of 2 Bluetooth devices at the same time.
