The soil sensor measures the soil temperature, soil moisture, the electrical conductivity of the soil, the complex dielectric permittivity of the soil and the electrical conductivity of the "water pores" contained in the soil hole. Both the conductivity of the soil and the water of the pores are automatically compensated by the temperature.

The ground sensor bases its measurements on the physics and behavior of an electromagnetic radio wave reflected in the ground. Based on the measurement of soil impedance through reflectometry in the frequency domain, the probe determines the dielectric permittivity. The complex dielectric permittivity allows the sensor to simultaneously calculate the soil moisture and the electrical conductivity of the soil. The sensor uses a frequency of 50 MHz, which minimizes the effects of texture and salinity, which makes measurements accurate on most hydroponic substrates.

The electrical conductivity of the "pore water" is calculated using algorithms based on soil moisture and soil electrical conductivity values.


Structural Components:

This sensor is designed to remain buried for many years in the ground. The probe consists of three main components:

·Marine grade stainless steel teeth set.
·Nylon. The outer shell is composed of this material.
·Epoxy resin. It provides internal electronic protection as well as a robust construction design for the probes.


Ground sensor communication:

The probe is available in an RS-485 digital version. The sensor incorporates a microprocessor to process the probe information in useful data. The data is then transmitted digitally to a receiving instrument with RS-485 communication. The RS-485 communication format has two data cables and has a personalized communication protocol.
