Minimum System Requirements

The Graphical User Application runs on 32-bit Windows 7 and above and is required to interface with the TriSonica Mini. As additional operating systems are supported, they will be listed here.

What is the First Thing I Should Do if I Have a Question About Functionality or Programming Unit?

The TriSonica Mini provides an extensive Help Menu accessible simply by typing ‘help’ at the Command Line.

What Are the Three Dimensions of Wind the TriSonica Mini Measures?

The TriSonica Mini provides precise wind speed and direction by measuring a combination of three axis of U (pitch), V (roll), and W (yaw).

Can the TriSonica Mini Measure A True Vertical Wind?

If you need a vertical wind measurement you can mount the TriSonica Mini sideways so that the U axis is measuring the vertical wind direction. If you are trying to measure eddy covariances you can mount two instruments such that one measures the U and V axes, and a second measures the W and V axes. The instruments can be synchronized to sample at the same time. We have designed a Dual-Axis Sensor Mount that is engineered to hold two TriSonica Minis at 90° angles with 0.1° accuracy.

Is the TriSonica Mini a flux instrument?

The current iteration of the TriSonica Mini has a +/- 15 degree angle of acceptance of vertical measurement before the shadowing effects of the mounting structure becomes noticeable, therefore it is not capable of measuring atmospheric flux. We have added a flux capable instrument to our road map and will announce that product’s availability when it is ready. To ensure that you hear about the latest releases or announcements from Anemoment, LLC, subscribe to our newsletter. For those requiring flux measurement capabilities today, we suggest you visit Applied Technologies, Inc. (one of our leading distributors) at as they have probes capable of capturing flux measurements in stock.

Does the TriSonica Mini Measure Yaw, Pitch, and Roll?

Yes, the TriSonica Mini’s compass measures yaw or direction, while its accelerometer measures both pitch and roll.

Can the TriSonica Mini Measure Accurately When Tilted?

The TriSonica Mini is able to measure accurately when tilted (up to a 15° tilt), such as on a UAV or buoy.

What is the TriSonica Mini made of?

The TriSonica Mini Wind Sensor and Tactical Weather Station are both constructed of DuPont™ Zytel®nylon resin. Zytel 80G33HS1L is a 33% glass fiber reinforced heat stabilized polyamide 66 resin engineered for demanding applications where outstanding impact resistance, high mechanical strength, stiffness and extreme temperature performance are required (learn more here).

What is the TriSonica™ Mini Data Output?

The TriSonica Mini outputs an ASCII string that can easily be store to a text file. We use a program called TeraTerm and it provides a logging function that will write the data into text file. It is then very easy to import the text file into Excel for processing.  We are working on a Windows Graphical User Application that also has logging capability.

What is the Optimal Height for Mounting the TriSonica™ Mini?

The height of the anemometer position is dependent on what you are trying to study. We have seen some installations that mount the TriSonica Mini a few inches above the beach/rocks and others that put it on 3 to 10 meter towers.

If you intend to mount the TriSonica Mini on a multi-rotor UAS or drone, researchers at the International Conference on Unmanned Aircraft Systems (ICUAS) have reported that influences from rotors are negligible at around 400 to 450 mm above the aircraft’s rotor plane. Our customers have mounted their TriSonica Mini as high as 18″ to 20″ above the rotor plane to negate any impact the blades might have on their readings.

If you are interested in measuring the wind speed at on a island, then we suggest that you put the TriSonica Mini high to avoid the turbulence caused by the island topology. The size of those island features will have an effect on how high you need to be. The higher you go the less of an effect the island will have on the airflow.

Available in a pipe-mount version, installation is simplified and streamlined. Will accommodate any 1/2″ schedule 10 pipe.

Is the TriSonica™ Mini Solar Cell Compatible?

The TriSonica Mini operates on an input voltage of 9V to 24V and requires about 360mW to operate. You can power the TriSonica Mini via a solar panel as long as the panel and battery pack produces a minimum of 12V.

What Is the Wiring Configuration of the TriSonica™ Mini?

The four wires coming out of the TriSonica Mini are:

  • Yellow – 9-36V (you will need to supply this power separately)
  • Red – RS-232 TXD (data out of the TriSonica Mini)
  • Green – RS-232 RXD (data into the TriSonica Mini)
  • Black (Ground)
What Is the USB Connectivity of the TriSonica™ Mini?

Our USB Interface Adaptor translates the RS-232 signals from the TriSonica Mini to a USB connection, and converts the USB 5V to 12V to power the TriSonica Mini directly. With the USB Interface Adaptor in place, a separate power supply is not necessary providing a single cable connection between a PC and a TriSonica Mini.

What is Your Order Fulfillment Policy?

Anemoment LLC fulfills all orders from our corporate headquarters in Colorado, USA. If you have an account with an international shipping company that you would like us to use to ship your order, please provide that information at the time you place your order. Otherwise, we will use the United States Post Office or UPS for all order fulfillment. Shipping options and associated costs are displayed and are selected by the customer at time of order.

Where Can I Find User Manuals?

The User Manuals for the TriSonica Mini family of products can be found near the top of this page under Downloads. The User Manuals available on the website may not match your unit exactly because the TriSonica Mini is configurable to add and remove fields to the user’s needs. The “display” command lists all of the fields and prints a table of what is enabled for display. You can turn outputs on and off, but you cannot change their order.

Where Can I Find Firmware Updates?

Firmware Release 1.9.0 (December 2019) is now available. It is recommended that all TriSonica Mini users update the firmware on their devices to Firmware Release 1.9.0. Firmware Release 1.9.0 provides a number of improvements designed to enhance your experience with your TriSonica Mini. Enhancements include:

  • Added Low Power Mode with internal and external wakeup. External wakeup should only be used with a Pipe-Mount version.
  • Modified data output tags to make them unique. Eliminating multiples Ps and Ds
  • Fix the bug where the temperature and humidity can get stuck outputting ‘nan’
  • Rewrote the humidity calculations to use partial pressures to determine molar mass. The calculations are no longer dependent on the previous temperature reading.
  • The calibration command was modified to accept a pressure value so that a more accurate value of molar mass can be calculated for determining the speed of sound.
  • Fixed long help for show, hide, decimals, tag, untag to display properly
  • Fixed Display and Decimals commands to show and set Humidity and Pressure decimals.
  • Added trisonicaid command to allow users to identify data streams from multiple instruments.
There are two files required to update your firmware: the GUI interface (to simplify the process), and the Firmware update itself. First, click here to download the GUI file. Then, click here to download the Firmware Release itself. To complete the update process, simply follow the following instructions:

1) Connect to your TriSonica Mini on the Settings page. 2) Click the browse button and find files on your computer. 3) Click the Update Button and the update begins. 4) Wait for the update to complete.

NOTE: Devices with Firmware Release 1.5.2 need to contact Anemoment directly in order to arrange for their device to be brought current with Firmware Release 1.74. The update process described above will not update these units.

Firmware Updates can now also be found near the top of this page under Downloads.
