TriSonica™ Mini Wind and Weather Sensor

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 perfect for drone-based (UAV/UAS) 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 5-36 VDC @ 350mW power.

No Moving Parts

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

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 unmanned 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.

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.

Anemoment Data Logger 222

What is the Anemoment Data Logger 222?

The Anemoment Data Logger 222 provides a complete integrated solution for your TriSonica™ Mini Wind & Weather Sensor. Gone are the days of hacking together a solution using multiple PCBs from various vendors to match voltage levels and power requirements for integrating a TriSonica Mini into your platforms.

The Data Logger 222 operating voltage range operates from a simple AC power adapter, a UAS battery, or a solar/wind charged battery system. Data is stored locally on a MicroSD card, or can be transmitted over a serial or WiFi data link.

For extreme conditions, the Data Logger 222 can be incorporated in a weather-tight enclosure making it suitable for remote deployments in challenging environments.
