  • Patent number: 11512995
    Abstract: Systems and methods for accurate measurement and transmission of water level parameters during weather events, such as floods, are provided. The solid-state system can effectively measure water level without utilizing moving parts, pumps, or floats and may implement an improved water level determination method that compensates for inherent sources of error. Additionally, the system may be comprised of a network of sensor units that can communicate weather measurements wirelessly via a hybrid mesh network consisting variously of wireless terrestrial radio, cellular, and satellite communication links. By doing so, the status of water level and other environmental parameters may be reported in real time to first responders and emergency planners.
