Common Applications

This sensor is meant to track surfaces that are perpendicular to the PCB that the sensor is mounted on. Common applications are for human-interface devices with dial-like or doorknob-like controls. The sensor would be mounted on a PCB inside and it would face a moving wall. The sensor would report a number of counts depending on how much the wall has moved which can be used for controls (e.g. after detecting 5 counts to the left, do something).

  • Other Applications:
    There is a wide range of other possible applications for this sensor. These would typically be any type of surface tracking that requires a right-angle view and could range from applications such as human-interface devices to industrial automation.
