The OWI-430 DSP-WIVIS™ is the most advanced present weather and visibility sensor ever made. The fully automated instrument provides accurate visibility, present weather and precipitation measurement in a single sensor. This next generation intelligent sensor uses all digital signal processing (DSP) for no-drift high-accuracy results. OSi`s patented environmentally adaptive algorithms use artificial-intelligence technology derived from over 100 million field hours of real-world data from our sensors installed around the world. The result is the most advanced weather sensor in the world.
