Our compact, robust meteorological instruments deliver unmatched precision and accuracy for use in unmanned aerial vehicles (UAV, UAS, drones) and other unmanned platforms, and are ideal for a wide range of applications, including environmental monitoring, precision agriculture and wind profiling.

TriSonica Mini 3D Ultrasonic Anemometer

Compact 3D Wind Sensor for UAVs

The TriSonica Mini is the world’s smallest and lightest 3D ultrasonic anemometer. Small enough to fit in the palm of a hand, it weighs just 50 grams and has no moving parts, making it an ideal ultrasonic wind sensor for UAVs and other SWaP (size, weight and power)-conscious systems.

The compact, lightweight system uses acoustic wave pulses to sense wind movements in three dimensions (pitch, roll and yaw), providing high-accuracy real-time wind data for small drones and other mobile platforms.

Four open measurement paths of just 35mm – engineered to provide minimal distortion of the wind field – provide measurement redundancy as the path with the most distortion is removed from the calculations.

The TriSonica Mini provides wind speed, direction and temperature data outputs, as well as measurement of all three air flow dimensions. Accurate measurement is maintained even at tilt angles of up to 15 degrees, making the anemometer ideal for moving platforms such as UAVs and USVs (unmanned surface vessels), as well as fixed locations such as UAV ground control stations (GCS).

The TriSonica Mini anemometer outputs an ASCII string via RS-232 that can easily be stored to a text file. Data emulation allows the system to be directly connected to existing off-the-shelf data loggers without costly changes to associated electronics. Data output is factory set to user requirements and includes the emulation of many common types of wind sensors, allowing the TriSonica Mini to be used as a convenient upgrade to older, bulkier devices.
