Size, Weight, and Power Optimized
The TriSonica Mini and the TriSonica Sphere are both SWaP-optimized making these mobile sensing systems ideal for UAS-based atmospheric research studies.

No Moving Parts
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 tool 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. Even with its small size it provides wind speed, direction, temperature, humidity, pressure, tilt, and compass data. The TriSonica™ Mini Wind & Weather Sensor can also provide measurements of all three dimensions of air flow. The open path provides the least possible distortion of the wind field. Four measurement paths provide a redundant measurement. The path with the most distortion is removed from the calculations to provide accurate wind measurements. Further, data output can be customized to user requirements. Available with a pipe-mount base accommodating any 1/2” DN15 Schedule 10 pipe. To further protect components and streamline your installation, wiring runs through the interior of the pipe when using this configuration.
The TriSonica™ Sphere Wind Flux Sensor is the 3D Sonic ideal for UAS-based atmospheric flux studies. With its more precise vertical wind measurements and its faster sampling rates (up to 100 Hz), the TriSonica Sphere was engineered specifically for atmospheric flux and turbulence research, including Eddy Covariance studies. The TriSonica Sphere’s unique spherical design (U.S. Patent No.: 11,268,974) dramatically reduces shadow correction while increasing the accuracy of vertical wind measurements. Its all aluminum construction enhances the devices’ durability while maintaining its SWaP (Size, Weight, and Power) advantage over competitive sensors. This makes the TriSonica Sphere ideal for UAS/UAV deployments. The TriSonica Spheres’ design and open path geometry enables it to effectively and accurately capture measurements of all three dimensions (U, V and W) of air flow with the least possible distortion of the wind field, especially vertical turbulences. It should be noted that the TriSonica Sphere does not include sensors for humidity, air pressure, or compass direction, but will measure tilt. The TriSonica Mini and TriSonica Sphere were specifically engineered for use on BlueHalo’s Atmospheric Characterization Weather Payload (WP-V3 ACP), providing a complete, customizable meteorological sensor suite that can easily be mounted on a variety of UAS platforms.
Anemoment Data Logger 422
LEFT: DL422-B (Board-only); RIGHT: DL422-E2 (in weather-tight IP67 rated enclosure supporting 2 TriSonica sensors)
A Fully Integrated Storage Solution
With its 4 serial instrument ports, 2 analog inputs, and 2 digital inputs, the Anemoment Data Logger 422 (DL422) provides a fully integrated solution for your TriSonica 3D Sensors. Gone are the days of hacking together a solution using multiple PCBs from various vendors to match voltage levels and power requirements for integrating TriSonica Sensors into your platforms. The Data Logger 422 operating voltage range operates from a simple AC power adapter, a UAS/UAV battery, or a solar/wind charged battery system. The DL422 stores data locally on a MicroSD card or can transmit the data over a serial data link.
The DL422 can easily be integrated via standardized connectors to support 3rd party radios, GPS, and batteries (UN38.3 certified). For extreme conditions, the Data Logger 422 can be incorporated in a weather-tight IP-67 enclosure making it suitable for remote deployments in challenging environments.
The DL422 is available in four options:
-
- DL422-B (no enclosure, board only) – Includes one 12-pin internal cable to connect to any TriSonica sensor, one 6-pin internal cable with additional cable-side connector to connect to 3rd party equipment (radio, GPS, etc.) Ships with both a 12-pin internal cable and a 6-pin internal cable w/cable-side connector.
- DL422-E1 (in IP-67 enclosure) – Includes SINGLE TriSonica sensor connection, two 6-pin cable-side connectors to connect to 3rd party equipment (radio or GPS), one 3-pin cable-side connector for power.
- DL422-E2 (in IP-67 enclosure) – Includes DOUBLE TriSonica sensor connection, two 6-pin cable-side connectors to connect to 3rd party equipment (radio or GPS), one 3-pin cable-side connector for power.
- DL422-E4 (in IP-67 enclosure) – Includes QUADRUPLE TriSonica sensor connection, four 6-pin cable-side connectors to connect to 3rd party equipment (radio or GPS), one 3-pin cable-side connector for power.
