1. A wake-up apparatus for a low power sensor node, the apparatus comprising:

  • a wake-up signal detector receiving and detecting a wake-up signal of a sensor node;

    a wake-up radio frequency (RF) circuit unit filtering and amplifying the wake-up signal; and

    a wake-up baseband transducer detecting a wake-up address from the wake-up signal and comparing and verifying the wake-up address with a wake-up address that is provided from a server managing the sensor node, and outputting an interrupt signal for transmitting a sensing event of the sensor node or outputting a wake-up address of another sensor node in an area where the interrupt signal is to be sensed if errors are not detected when the wake-up address is verified.
