Some digital meters show soil moisture levels to a decimal point or percentage, making them more accurate than an analog meter with a 1-to-10 scale. Calibration features also can help with accuracy.

The soil moisture sensor module , built around the LM393 comparator, gives an active-low (L) level output when the soil is dry (determined by a pre-setted threshold value). This digital output (wet ...

Soil moisture tester circuit diagram. A quick look at Figure 2 is enough to ascertain that the full circuit is barely more complex than the block diagram. It’s only really the supply that is extra.
