Tips: How is the output voltage related to soil moisture levels?

The output voltage (ranging from 0 to 3.0 VDC) increases as the soil moisture content rises. In dry soil, the sensor’s output voltage is lower, whereas in moist soil, the voltage rises. Users can interpret these readings to determine the exact soil moisture levels and can set thresholds for specific plant needs. This feature is particularly useful in automated irrigation systems where the sensor can control water flow based on soil moisture levels, conserving water and maintaining optimal plant health.
