Abstract: A method of detecting water within a pit of an elevator shaft including: emitting an electromagnetic wave from an electromagnetic wave source towards a bottom of an elevator shaft; detecting a reflected electromagnetic wave of the electromagnetic wave using an electromagnetic wave detector; and determining whether water is present within the pit of the elevator shaft in response to the reflected electromagnetic wave.
