Bio-signal monitoring device

A bio-signal monitoring device comprising:

• an electrocardiogram detector configured to detect an electrical signal from a heart of an object and output an electrocardiogram signal;
• one or more sensor units comprising a breathing rate sensor, an acceleration sensor, or a temperature sensor, or a combination thereof;
• a controller configured to process the electrocardiogram signal, a sensing signal received from said one or more sensor units or both;
• a connector configured to:
• be coupled to said one or more sensor units and
• transmit, to the controller, a sensing signal from said one or more sensor units;
• and
• a communicator configured to communicate with an external electronic device,
• wherein the controller comprises:
• a first signal analyzer configured to receive the electrocardiogram signal and generate first analysis data by analyzing the electrocardiogram signal;
• a second signal analyzer configured to receive a sensing signal from said one or more sensing units and generate second analysis data by analyzing the sensing signal;
• and
• a signal processor configured to transmit the electrocardiogram signal or the sensing signal to the external electronic device according to a request signal.
