Freespace Sensor Modules are used by engineers to add inertial motion control to a product 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.
