The reason you need soil moisture is because of the benefits it gives your .
AO (Analog Output) generates analog output voltage proportional to the soil moisture level, so a higher level results in a higher voltage and a lower level results in a lower voltage. DO (Digital Output) indicates whether the soil moisture level is within the limit. D0 becomes LOW when the moisture level exceeds the threshold value (as set by the potentiometer), and HIGH otherwise. How Does A Soil Moisture Meter Work? A soil moisture meter has a long metal probe that is inserted into the soil about 4 inches deep. Attached to the probe is gauge that typically ranges from 1 to 10. A reading of 1 indicates the soil is extremely dry whereas a 10 means that the soil is wet. A reading in the middle indicates the soil is moist.
Soil moisture sensors measure the water content in the soil and can be used to estimate the amount of stored water in the soil horizon. Soil moisture sensors do not measure water in the soil directly. Instead, they measure changes in some other soil property that is related to water content in a predictable way.
