1. A sensor applicator assembly for a glucose monitoring system, comprising:
an external container;
an internal container disposed inside the external container;
a plunger body disposed inside the internal container;
a sensor module disposed below the plunger body;
a needle withdrawing body disposed inside the plunger body;
a needle coupled to an inner side of the needle withdrawing body;
an elastic plunger spring which is disposed inside the plunger body and extended from a compressed state to move the plunger body and the sensor module downward within the internal container; and
a needle withdrawing elastic spring which is disposed inside the needle withdrawing body and extended from a compressed state to move the needle withdrawing body and the needle upward,
wherein a top end portion of the elastic plunger spring is in contact with an inner top surface of the internal container,
wherein the sensor module includes a pod, a PCB disposed in the pod, a battery disposed in the pod, and a sensor probe having one end portion protruded from a lower surface of the pod and the other end portion disposed in the pod, and
wherein the pod and the plunger body are moved together from a first position to a second position due to elastic force of the elastic plunger spring.
