We are offering soil moisture sensor. The qt-sm100 can be used for various types of soil moisture for fast measurements, based on the proven tdr(time domain reflector with intelligent elements) technology. For the direct measurement of soil or other medium dielectric constant, according to the relationship between the dielectric constant and soil moisture derived the soil water content.
