1. A data logger, including an out-body equipped on an outside of a container body and an in-body equipped on an inside of the container body, comprising:
a sensor configured to sense a change in a gravitational acceleration of the data logger and a change in a rotation angle of the data logger, and generate a sensing signal;
a first temperature sensor of the in-body configured to sense an internal temperature of a freezer;
a second temperature sensor of the in-body configured to sense an internal temperature of a refrigerator;
a communication module configured to receive configuration information including a sensing period and threshold values of the data logger from a portable reader; and
a microprocessor unit configured to receive the sensing signal from the sensor, receive the sensing period and the threshold values from the communication module, generate sensing values corresponding to the sensing signal, compare the sensing values with the threshold values, determine whether an abnormal state occurs in the data logger according to a result of the comparison, generate and transmit to a server normal log information at each of the sensing period when the abnormal state does not occur in the data logger, and generate and transmit to the server abnormal log information whenever the abnormal state occurs regardless of the sensing period,
wherein the microprocessor unit is configured to receive and process an output signal of the first temperature sensor and ignore an output signal of the second temperature sensor,
wherein the microprocessor unit is configured to determine that the data logger is in a normal state when each of the sensing values is less than each of the threshold values about the change in the gravitational acceleration and the rotation angle, and determine that the data logger is in the abnormal state when at least one of the sensing values is greater than at least one of the threshold values about the change in a gravitational acceleration and the rotation angle.
