Lightweight Data Logger for UAV Weather Sensors

Anemoment has launched the DL422, the company’s lightest and most advanced data logger to date. With the ability to collect data from up to four serial instruments, two analog inputs, and two digital inputs, the DL422 can also connect to GPS receiver and radio transceiver modules. Weighing just 30.5 grams, the miniature SWaP (size, weight and power)-optimized data logger is ideal for integration into UAVs (unmanned aerial vehicles).

Supporting the entire TriSonica family of ultrasonic 3D anemometers as well as other serial ASCII-based instruments, the DL422 is available as a circuit board (DL422-B) or in a IP67 rated weather-tight enclosure with either a single (DL422-E1), double (DL422-E2), or quadruple (DL422-E4) TriSonica sensor connection.

The fully integrated and seamless data solution does away with the need for creating a custom solution using multiple PCBs from various vendors to match voltage levels and power requirements in order to integrate a TriSonica Sphere Wind Flux Sensor or TriSonica Mini Wind & Weather Sensor into UAV platforms.

The DL422 ensures users’ ease of integration via standardized connectors for 3rd party radio, GPS, and batteries (UN38.3 certified). To enable maximum power flexibility, the DL422’s operating voltage range operates from a simple AC power adapter, a UAS/UAV battery, or a solar/wind charged battery system. Furthermore, data is stored locally on a MicroSD card or can be easily transmitted over a serial data link.

Stephen Osborn, CTO of Anemoment, commented: “With the release of the TriSonica Sphere and its ability to accurately measure atmospheric turbulence and flux measurements, users have been searching for a data logger that supports the Sphere’s unique capabilities. The Data Logger 422 not only delivers on those requirements but does so with a size and weight optimized for UAS deployments.”
