Motion Detector

A Motion Detector (MD-BTD) can be used with TI calculators, but the motion detector requires an interface. These interfaces do not work will all calculators, and some interfaces have been discontinued. Unless you already have an interface, do not purchase this motion detector for use with your calculator.
