Beschreibung
Zusammenfassung:	The present invention discloses an event detection method for waking up a portable electronic device and an action sensor using same. The event detection method includes the steps of: under a normal operation mode, sensing action events by the action sensor with a first data sensing frequency, wherein the action sensor operates by a normal current to detect the action events; entering into a sleep mode; under the sleep mode, detecting a wake-up event by the action sensor with a second data sensing frequency, wherein the action sensor operates by a weak current to detect the wake-up event, wherein the weak current is smaller than the normal current, and the second data sensing frequency is not higher than the first data sensing frequency; and returning to the normal operation mode when the wake-up event is detected.
