What technology does the Baseline biSensor use?

Baseline’s patented soil moisture sensors use TDT (time domain transmission) technology to provide sensors that are so much more sensitive (which means they are highly responsive to changes in moisture levels) than previously available sensors. Baseline sensors can reliably track changes in soil moisture content at less than 1/10th of a percent.

Baseline’s soil moisture sensors work by sending a high frequency pulse of electricity down an embedded wire path. The high frequency of the pulse causes the sphere of influence of the pulse to move outside the sensor blade and into the soil around it. When the pulse travels through moisture, it slows down. The sensor measures the speed of the pulse, and then converts this measurement to a moisture content reading.

Baseline's soil moisture sensors report true volumetric moisture content (VMC) and reported to be ± 3 percent in accuracy within most soil types.
