Systems, methods, and devices for soil moisture detection

A soil moisture detection device, the device comprising:

• a processing unit;
• a conductive sensor configured to:
• detect a conductive soil moisture raw data by a DC resistance measurement on a conductive voltage divider for a soil, wherein the soil operates as a variable resistor wherein a soil resistance is inversely proportional to the soil moisture;
• and
• a capacitive sensor configured to
• detect a capacitive soil moisture level raw data by an AC impedance measurement on a capacitive voltage divider for the soil, wherein the soil operates as a variable capacitor wherein a soil impedance is inversely proportional to a current.
