acually I have 1 kilograms a type of soil and every 10 minutes I add 10 grams of water and measure the output, it is voltage output but it is not same in every test. what do you mean about the averaging? for example in one of my test differences between every added water, the outputs are like this: 0.1-0.4-0.3-0.5-0.2-0.6-0.9
the other one in the same situation are like this: 0-0.3-0-0.3-0.5-0.5-0-0.8
what is your suggestion now?
