Hi , i want to set a 3 levels sensor for a drinking water in a kettle,the water is dispensing from the kettle to a cup; the two high levels have a led for indication and the low level have an output to Arduino to run a small pump, by the way, i want to use an ultrasonic sensor but it will be destroyed by the vapor from the hot water and the capacitive sensor is expensive, so how can i do that?
