The soil moisture sensor is a device to measure volumetric water content in the soil. The sensor measures volumetric water content indirectly, without removing moisture, by using other parameters of soil like electrical resistance or conductance, dielectric constant and interaction with other neutrons. The result may vary depending on environmental factors like soil type, temperature, and conductivity, so it must be calibrated.
