Abstract
Provided is a data logger. A data logger includes 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 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.
