Introducing the




The TriSonica Sphere was engineered from inception to deliver more precise vertical wind measurements coupled with fast sampling rates (up to 100 Hz) making it ideal for UAS-based atmospheric flux and turbulence research, including eddy covariance studies.

The TriSonica Sphere’s unique spherical implementation (U.S. Patent 11,268,974) dramatically reduces the effects of wind shadowing and increases the accuracy of vertical wind measurements.





Looking for a 3D Wind and Weather Sensor?

Look no further than the TriSonica Mini Wind and Weather Sensor, the world’s smallest and lightest 3D ultrasonic anemometer. Compact, light, and efficient, the TriSonica Mini is a highly accurate tool for atmospheric monitoring, weather reporting, and ecosystem research. Even with its small size it provides wind speed, direction, temperature, humidity, pressure, tilt, and compass data.

The World’s Smallest and Lightest 3D Sonic Anemometer


The TriSonica Mini Wind & Weather Sensor is a compact (measurement path of just 35 mm), lightweight (less than 50 grams), low velocity anemometer. It is small enough to fit in the palm of your hand, yet it is a powerful and highly accurate mobile sensing system engineered for atmospheric monitoring, weather reporting, and ecosystem research.

Its size and featherweight profile make it perfect for uncrewed aerial systems (UAS), while the fact that it has no moving parts, thus eliminating maintenance issues, enables it to be stationed on fixed or portable towers for real-time 3-dimensional air flow measurements.

Say goodbye to cumbersome and bulky cup-and-vane anemometers, and hello to the TriSonica Mini Wind & Weather Sensor.


The TriSonica Mini can fit in your hand, measuring only 9.1cm x 9.1cm x 5.2cm.


The TriSonica Mini is very light, weighing just 50 grams; about the weight of a golf ball.


The TriSonica Mini is highly energy efficient, drawing only 5-32 VDC @ 30mA power.

No Moving Parts

This enables it to be stationed on fixed or portable towers for worry-free, real-time air flow measurements.

For me, size and weight are key attributes. The TriSonica Mini is small, easy to put on the sUAS and it doesn’t really take much power. I can always add more instruments to my payload, especially if they all weigh nothing and they don’t take up any space.

How are TriSonica Sonic Anemometers being used?

We engineered the TriSonica sonics to sense wind movements in three dimensions (Tri) using ultrasonic acoustic wave pulses (Sonica); thus its name, TriSonica. People immediately perceived the advantages this new product represented over bulky and cumbersome cup-and-vane anemometers. Its size, weight, power requirements, and lack of moving parts made it ideal for a variety of mobile sensing applications.
