As part of an eacape room game, i need to be able to sense when a water level reaches a specific volume, so not any lower, not any higher.
When this TARGET level is reached, a relay will be triggered.
To be sure there is no false trigger as the water level rises through the TARGET level to a level too high, i need to be able to have a timed delay before the trigger.
Im wondering if this is achievable with an ultra sonic sensor.. Has anyone attempted this and even better are there any projects known out there that have arduino code available?
Thanks for any help!
