1. A motion sensor module for an electronic device, the motion sensor module comprising:
- a housing;
an electrical contact configured to receive power from the electronic device upon maintaining a physical connection with a corresponding electrical contact of the electronic device;
an inertial measurement unit configured to generate motion data indicative of motion of the motion sensor module,wherein the inertial measurement unit has a sample rate of at least 100 kilohertz (kHz);
a memory configured to store the motion data generated by the inertial measurement unit; and
a wireless transmitter configured to automatically transfer the motion data to the electronic device without requiring user input when the housing is positioned proximate to an accessory bus of the electronic device.

Abstract
Various embodiments concern motion sensor modules able to monitor movement. A motion sensor module can be detachably connected to an electronic device to which the motion sensor module transfers motion data. In some embodiments, the motion sensor module is connected to an electronic device associated with an individual. In other embodiments, the motion sensor module is embedded within an article of clothing worn by the individual (e.g., a shirt, swimsuit, or shoe). The motion sensor module includes at least one inertial measurement unit (IMU) that generates motion data indicative of the motion of the motion sensor module as a whole.
