Interviewer:Discuss what all you will in a real life water heater controller if you were to add anything other than temperature sensor and flow rate valve? A: I would have level sensors and alarms to identify any interlock failures like overheating. Interviewer: but in the given test requirement why would you need a level sensor? (wasn't the question about additional sensors and not required sensors? do you want to stick to the test requirements or do you not want to stick to it. decide first plz)
