Thank you for the prompt response.
The information is inconsistent with the results I am seeing.
I see a low number on the soil moisture sensor that fluctuates up and down between 420 and 460 when the sensor is completely immersed in water for 24 hours.
When it was outside of the water and dry, it stabilized at 700 reliably without any fluctuations.
My three questions are:
1. is the soil sensor already returning a "relative humidity" value another NOT just returning a moisture value? BTW, when I say relative humidity, I mean a value that is calculated based on the current temperature.
2. If I need to calculate the relative humidity from the soil moisture sensor, could you please tell me how to do that based on the 420 - 700 range of values? ... what is the formula?
3. Do these sensors need to be calibrated somehow?
Thank you very much.
