The V2.0 Capacitive Soil Moisture Sensor is a slim 10cm x 2.4cm PCB probe operating from 3.3V to 5.5V at only 5mA current, outputting an analog voltage through a PH2.54-3P connector. The capacitive soil moisture sensor measures moisture by detecting changes in the soil’s dielectric constant — as water content increases, the dielectric constant of the soil increases, and the sensor’s capacitance changes accordingly, without passing any electrical current through the soil itself.
This non-current-through-soil approach is the fundamental advantage of the capacitive soil moisture sensor v1 2 and its V2.0 successor over resistive sensors — because no current flows between exposed electrodes, there is no electrolytic corrosion of the probe, making the capacitive moisture sensor significantly more durable for long-term buried installation, especially in saline soils where resistive sensors fail quickly due to mineral-driven conductivity interference. The V2.0 designation refers to an improved board design over V1.2 with better component placement and protective coating for greater long-term stability. The v2.0 soil sensor price reflects this improved longevity and the ultra-low 5mA power draw that suits battery-powered solar garden IoT nodes.
One practical trade-off: the capacitive humidity sensor reading is influenced by soil temperature — the dielectric constant of water changes with temperature, so readings taken in very cold or very hot soil conditions may require temperature compensation for accurate moisture percentage conversion. This StemVolt sensor is well-suited for engineers building long-term soil monitoring systems and practical agriculture automation electronics projects.
