Pond oxygen readings are checked with a hand held unit called an oxygen analyzer. This is attached to a probe that supplies the analyzer with the data. When the analyzer is first turned on it is digitally calibrated. Then the probe is submerged into the water and the ppm is digitally displayed.
I want to connect the probe directly into the serial port on my laptop, configure the protocol, and write the appropriate VB code to calibrate and record the readings to my recordset.
Does anyone have any knowledge on this or have any idea how much trouble it is going to be?
