Messwertkalibrierung DIY EC Messgerät:
|

300mL dest. Wasser in 500mL Becherglas auf Magnetrührer
|
||||
Wasser temperiert auf 25°C und durchgehend temperatur gehalten
|
||||
Temperatursensor und DIY EC-Probe in Flüssigkeit gehalten
|
||||
EC Sensor in Flüssigkeit zur Referenzmessung
|
||||
Magnetrührer auf langsamer Stufe (keine Strudelbildung)
|
||||
Messwert per Tastendruck erfasst (time,tempReservoir,ECadcCalib,ECadc,ECadcAdjusted,sm)
|

temperatur d. flüssigkeit
|

Roher ADC Messwert
|

angepasster ADC Messwert (linear gemappt nach abweichung vom referenz adc wert, referenz adc wert vorher ermittelt und eingegeben in code)
|

Soil Moisture ADC Messwert (der mit dem RG174 Kabel)
|
||||
|
||||
manuell abgelesen: EC wert
|
||||
|
||||
Erster Messwert nur dest. Wasser.
|
||||
Weitere Messwerte jew. nach hinzufügen erst wenigen tropfen NaCl Lösung. Später mehr bis zu 6mL pro Messung.
|
||||
|
||||
Bläschen an Elektroden durch pusten entfernt wenn sie sich gebildet haben
|

|
||||
Werte in 20230505_NaCl.csv bzw auswertung in ..ods
|
||||
|
||||
Polynom 10. Grades erstellt mit python approximate.py
|

Temperaturabhängigkeit:
|

NaCl Lösung auf etwa 1500uS/cm angemischt
|
