Water leak sensor management method, water leak sensor performing the same and storage media storing the same

The present invention relates to a water leak sensor management method. The method of managing a water leak sensor which is installed in an underground pipe comprises: (a) a step of detecting an operation time of the water leak sensor through a timer in the sleeping mode; (b) a step of detecting a sensor measurement type by converting the sleeping mode to the standby mode during the operation time of the water leak sensor; and (c) a step of determining whether to perform an operation to a transceiving component of the water leak sensor and receive an external command according to the sensor measurement type, or convert from the standby mode to the operation mode. Accordingly, power consumption of a battery can be minimized by subdividing the operation of the sensor.
