A method for monitoring a ball used for an athletic activity includes detecting movement of the ball at a first time, using a sensor module coupled to the ball, determining that the movement of the ball corresponds to a predetermined activation movement, entering an active state of the sensor module in response to the determination that the movement of the ball corresponds to the predetermined activation movement, and detecting movement of the ball at a second time, using the sensor module in the active state.
