Custom OFF:
Moisture level is calculated based on default
dry and wet definition:
Dry (0%AD) AD: 70
Wet (100% AD) AD: 500
Soil Moisture = (moisture AD – 0%AD) *
100% / (100% AD – 0%AD )
Example: when sensor moisture AD is 310,
calculated moisture is:
(310 – 70)*100% / (500-70) = 56%.
This is a fixed slope rate linear system.
Custom ON:
When pot soil at dry or wet condition is not
giving the moisture sensor output value that is
close to its default assumption, it will give
inaccurate moisture level results. It is
commonly happening with different soil type
