Systems, methods, and devices for soil moisture detection

This invention describes a device that measures how much water is in soil by using two different electrical methods. One method measures how easily electricity flows through the soil with a steady current, while the other measures how the soil resists changes in an alternating current. By combining these two measurements, the device aims to provide more accurate readings across various soil types, with the steady current measurement specifically timed by a p-channel metal-oxide-semiconductor field-effect transistor.

Why it matters: While the core sensor technologies are established, advancements in low-power microcontrollers and edge computing since 2024 could make the complex data fusion from both sensor types more cost-effective and efficient, enhancing the system's promised accuracy across diverse soil profiles.
