The Ultrasonic Wind Speed and Direction smart sensor is designed to work with HOBO®
stations and is powered by its own built-in solar panel. The smart sensor has a plug-in modular
connector that allows it to be added easily to a HOBO station. All sensor parameters are stored
inside the smart sensor, which automatically communicates configuration information to the
logger without the need for any programming or extensive setup. Note: This sensor has been
modified to work with Onset station loggers only.
