An electronic device includes a circuit board having a signal detection terminal disposed on a first surface thereof and a ground terminal disposed on a second surface thereof and extending vertically so that the first surface and the second surface face each other in a horizontal direction, a monitoring terminal connected with the signal detection terminal, and a microcontroller unit (MCU) determining whether there is submersion by monitoring a voltage at the monitoring terminal. According to the present embodiments, it is possible to prevent hypersensitivity-induced misdetection due to condensation and dew. It is also possible to stepwise respond to submersion and determine whether the monitoring circuit normally operates to precisely detect submersion.
