Hi. I´m not bidding on your project at the moment, but I´d like to know more about it. I work in a Catchment Basin Committee in Brazil, where we monitor the level of water in rivers, wells and reservoirs related to drought (low water level), floods (high water level) and variations in the level over time. Would your device only advise when a fixed level was passed (like a switch, on or off), or could it measure multiple levels and advise us about the level in real time (a series of sensors)? Please send me more information, we may be able to install and test it here. Thanks, David
