Scientists at North Carolina State University (NC State) developed the wireless Contactless Moisture Estimation (CoMEt) system to measure soil moisture at multiple depths in real time. NC State's Usman Mahmood Khan said, "If we know how far the signal has traveled, and we measure how a wireless signal's wavelength has changed, we can determine the phase shift of the signal. This, in turn, allows us to estimate the amount of water in the soil." An above-ground wireless device transmits radio waves into the soil, receives the signals reflected back, and measures the phase shift. The researchers said CoMEt could help inform irrigation practices to improve crop yield and lower agricultural water usage. .... '
