SELF-CONTAINED, BUOYANT, AND WATER-TIGHT WIRELESS FLOOD DETECTOR

摘要

A floatable flood detector has a watertight housing which carries internally a wireless transmitter and a fluid sensor. In the presence of sensed fluid, an alarm message can be transmitted by the transmitter to a displaced monitoring unit. The sensor has a portion exposed to the fluid of interest, outside of the housing. The antenna is carried, at least at a fluid level, relative to the floating housing.
