Data logger having derachible battery for supplying power for outer sensors and rebroadcasting system using thereof

Abstract

The present invention relates to an apparatus attached to an object, for measuring physical quantities of the corresponding object, and more particularly, to a data logging apparatus provided with a separate power supply for driving external sensors, which is provided with a separate power supply for sensors, a plurality of replaceable sensors for measuring physical quantities of the object, and monitoring means for monitoring disassembly of the main body. The data logging apparatus of the present invention, which is provided with a separate power supply for driving external sensors, comprises a main module including an acceleration sensor, a memory unit, a control unit embedded with a clock unit for operating a measurement value of the acceleration sensor and storing the operated measurement value into the memory unit in a time series, and a first battery for supplying power to the acceleration sensor, the memory unit, and the control unit; a second battery detachably installed at one side main unit; and a sensor mounting module installed with a plurality of sensor resting units so that sensors can be attached and detached, for receiving the second battery inside so that power of the second battery can be supplied to the sensors installed in the sensor resting units, and transferring measurement signals of the sensors to the control unit.
