Water recognition system, electronic device including the same, and method of recognizing water thereby

A method of recognizing water by an electronic device, the method comprising:

• generating, by a first integrated circuit, a first detection result based on a resistance detected from at least one first pin of a connector of the electronic device, the connector comprising a plurality of pins;
• generating, by a second integrated circuit, a second detection result based on a resistance detected from at least one second pin of the connector, when the first detection result indicates that water is detected in the connector;
• and
• generating a first recognition result indicating that there is water in the connector, when the first and second detection results both indicate that water is detected.

A water recognition system comprising:

• a configuration channel (CC) integrated circuit connected to a CC1 pin and a CC2 pin of a connector defined in a universal serial bus (USB) Type-C interface;
• and
• the CC integrated circuit configured to,
• receive, from outside of the CC integrated circuit, a first water detection result through a first pin of the connector,
• enter a water detection mode based on the first water detection result, and
• detect, through a second pin of the connector, whether water is present in the connector when in the water detection mode.
