Measure distances up to 24″ with .250″ resolution using this Ultrasonic Distance Measurement expansion for Fusion Series controllers. Up to 4 of these expansion modules may be chained together onto a single UXP port of a Fusion controller. Since Fusion controllers have 2 UXP ports, up to 8 distance sensors may be used with a single Fusion controller. To use this expansion, simply run our Base Station Software and use the Ultrasonic Distance Measurement options in the software. This expansion works best with hard flat surfaces that reflect ultrasonic audio signals.
