water, and the displayed moisture readings are
much higher than 10% (e.g.40%).
Solution:
Enable the custom mode and adjust the 0%AD
value.
Calculate the 0%AD value with the formula:
Soil Moisture = (moisture AD – 0%AD) *
100% / (500 – 0%AD )
If:
Now AD = 183
100%AD = 500
Target Soil Moisture Reading = 10%
Then:
10% = (183 - 0%AD)*100%/(500 – 0%AD )
Result: 0%AD = 147(take the Integer part)
