Probe for the continuous monitoring in real time of chemical parameters of interest directly in the ground and system for the continuous monitoring in real time of said chemical parameters of interest

A probe for the continuous monitoring in real time of parameters of interest directly in the ground comprising,

• a substrate with at least two faces,
• at least one conductive material track arranged on at least one of the at least two faces of the substrate, with a zone adapted to act as an electrical contact terminal outside of the probe,
• a conductive region with reference electrode functions, with a zone adapted to act as an electrical contact terminal outside of the probe,
• at least one passivating material layer arranged such that it partially covers the at least one conductive material track and leaves at least two free zones thereof, one of said free zones corresponding to the electrical contact terminal of the at least one conductive material track, and
• at least one sensor element sensitive to at least one of the parameters of interest to be monitored in the ground, deposited in at least one of the free zones of the at least one conductive material track.
