Hi everyone,
I just purchase a Dissolved Oxygen Kit (Dissolved Oxygen Kit | Atlas Scientific), and I would like to read DO values and display on LCD. I uploaded the source code from: https://www.atlas-scientific.com/_files/code/do-i2c.pdf , but it just display on Serial Monitor. I don't know how to get a variables of DO sensor.
I try to modify the source code, then I can get the DO values, but I can't send the commands to circuit to calibration data. Can somebody help me please?
Thanks.

Why does your code look nothing like the code on the web site?

Maybe it has something to do with this part of the code:
/* //uncomment this section if you want to take the ASCII values and convert them into a floating point number.
DO_float=atof(DO);
sat_float=atof(sat);
*/

I get the same problem for atlas scientific dissolved oxygen sensor.
Was trying to figure out the problem for more than a week. Contacted their support staff too but no solution.
Would be going for this one instead
It has all the necessary parts for Dissolved Oxygen Kit and has software code too for arduino.
