What is the TriSonica™ Mini Wind and Weather Sensor?

The TriSonica Mini Wind and Weather Sensor is 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.


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 9-36 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 is the TriSonica™ Mini being used?

We engineered the TriSonica Mini 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 applications.

Aerial Applications

See how research agricultural engineer Brad Fritz uses the TriSonica™ Mini out in the field (no pun intended).

Atmospheric Profiling
