A sports helmet notification system to be carried by a helmet has a microcontroller in connection with an accelerometer that measures acceleration in three mutually orthogonal directions, a memory device and a notification device. The microcontroller has a predetermined logging setpoint and a predetermined notification setpoint. The microcontroller is programmed with instructions to record an event in the memory device upon receiving acceleration data from the accelerometer that exceeds the logging setpoint and to activate the notification device upon receiving acceleration data from the accelerometer that exceeds the notification setpoint. |
