Calypso Ultrasonic : the latest generation wireless wind sensor

Posted on31 October 20176 th 20242 comments

Ultrasonic anemometers-weathervanes for yachting came up just over 15 years old. Among the best known we can cite those of the American Airmar and French LCJ Sensors. Equipped with sophisticated electronics, these sensors without moving mechanical parts have the double advantage of being much more robust than traditional sensors, and provide much more precise data. They can also integrate other sensors as a barometer, gyroscope, electronic compass and sometimes even GPS.

The first ultrasonic sensors were equipped with a cable for power and data transfer. The manufacturer LCJ Sensors, building on the success of its CV3F sensor marketed since 2001, designed the CV7SF range, wireless models whose data is transmitted over a radio frequency to a receiver which converts it to NMEA (0183 or 2000). Power is supplied by solar cells on the sensor cap, and different output connection interfaces are offered depending on the models.

A new actor, Spanish Calypso Instruments, has just designed a completely new concept wireless sensor, the Calypso Ultrasonic Portable, whose characteristic is to be featured with a Bluetooth Low Energy Transmission Protocol (Bluetooth 4.1), which offers many advantages.
