A float switch is different than a standard water sensors.  Instead of using metal probes to detect the presence of water, a float sensor uses a mechanical float that rises as a the water level rises. They're great for use in tanks or sump pits, as an input device to an alarm or automation system.  When the water level rises, the float switch triggers a dry contact output connection.
