Freespace Sensor Modules are used by engineers to add inertial motion control to aproduct without having to learn about motion sensing or MEMS. These compact modules, the smallest of which is 9mm x 19mm x 2.5mm, are pre-calibrated for mass production, provide a well-documented API for interpreting motion, and provide data such as cursor position, linear acceleration, angular position, and angular velocity to enable the creation of novel applications.
