PURPOSE: A sensor node equipped having a wake-up module, a wakeup sequence control device, and a method thereof, are provided to control the wakeup sequence of MCU by using a hardware module. CONSTITUTION: If a beacon frame is transmitted or received, a MCU(200) confirms the information of the beacon frame. A MCU establishes registers. MCU converts a present mode into a sleep mode. If the interrupt is inputted, the MCU is converted from the sleep mode into an active mode. A wake-up module(300) multiplies the counter value in case of establishing the registers. A wake-up module outputs the interrupt according to the comparison result of the counter value and the BI(Beacon Interval) value identified from the beacon frame. |
