We’ve redesigned our new Motion Detector! You will recognize the case, as it is the same shape as before, but we have made two very important changes.

First, the minimum working distance has been reduced to just 15 cm. That means you can move your experiments closer, wasting less lab space. The cone of sensitivity is narrower at shorter distances, so simply moving your target closer will often make the experiment setup easier and data better.

The other change is hidden beneath the pivoting sensor head. A switch allows you to tailor the sensitivity to your experiment. With most experiments, you will want the “Normal”, or full sensitivity position. However, if you have a very reflective target you can choose the “Track” mode, which reduces the sensitivity. In “Track” mode the Motion Detector is much less sensitive to stray objects in the room or on the desktop near your experiment. Again, setup is easier, so you can concentrate on the science or math!
