Brunnenfüllstandsmessung mit Pumpensteuerung

Zur Überwachung des Füllstandes in einem Brunnen ( ca 6 m tief ) habe ich eine Messung mit Drucklufteinperlung über einen Schlauch in den Brunnen mit einer Aquarienluftpumpe installiert. Der Druck in dieser Leitung wird mit einem Drucksensor MPX 10 DP gemessen und das Ausgangssignal mit 2 OP (LM1458N) für den Eingang eines ATTiny 13 (A) verstärkt.
