Abstract: A method for dynamically managing power consumption, as well as a wake-up method, is disclosed for a wireless weighing platform. The method is initialized by setting both light and deep sleep period, entering a normal operating state, and starting light sleep timing. As long as no weighing operation is detected and the light sleep period has not expired, the method seeks to detect the weighing operation.

If no weighing is when the deep sleep period has expired, the wireless weighing platform enters a deep sleep state, by turning off power supply other than that for an acceleration sensor. If the acceleration sensor detects an effective vibration while in the deep sleep state, the normal operating state is restarted.
