doValue - Analog DO Sensor for Arduino
From the downloadable Arduino code the calculation of the doValue is dependent on SaturationValueTab[0] and (SaturationDoTemperature+0.5).
1. Can you explain how the SaturationValueTab array is used with the measured temp? Is there an associated table that explains the temp for each of the array values?
2. For the SaturationDoTemperature why add the .5?
3. How do I know that the reading(s) that I get are correct? Can I compare to a known DO level?
4. Does the barometric pressure have any affect on the reading? If so, what is the effect and can it be compensated for?
Thank You,
