Tips: The principle of a portable soil moisture meter

The portable soil moisture meter transmits a signal of a certain frequency, and the signal source probe transmits to the soil end, and some signals are reflected back to the transmission line due to the impedance mismatch, thereby forming a standing wave superposition with the original signal, since the reflectivity depends on the soil of the soil. The dielectric is always effective, and the dielectric constant of the soil has a linear relationship with the water content of the soil, so that the standing wave superposition signal can be detected to obtain the soil water content.
