Sample code
Higher accuracy
Using the free downloadable arduino sample code, a one point calibration can be
performed. The calibration procedure does not use any chemical buffer solution, instead
you use the open air to calibrate your probe to 100% saturation.
If more accuracy is required, Atlas Scientific offers a wide range of embedded D.O.
monitoring products that are significantly more accurate than this device.
