1. A sensing apparatus, comprising:
a voltage measuring unit configured to measure a voltage of a battery when power is supplied thereto;
an environment information measuring unit configured to measure environment information for the battery when power is supplied thereto;
a connector unit configured to output a first connection signal when being connected to the battery and output a second connection signal when being connected to an external battery management system (BMS);
a power unit configured to supply power to at least one of the voltage measuring unit and the environment information measuring unit according to an operation mode; and
a control unit configured to control the operation mode of the power unit based on which of the first connection signal and the second connection signal is received from the connector unit and residual amount information of the power unit,
wherein the control unit is configured to control the operation mode of the power unit to a power supply mode or a sleep mode based on whether the first connection signal is received, whether the second connection signal is received, and the residual amount information.
