Based on Low of Electromagnetic Induction, a uniform alternating magnetic field is provided to plant stem through excitation module. Sap flow cuts the magnetic flux lines, inducing electromotive force signal on sensor. The signal is processed by signal processing circuit, filtered, and amplified. Af...
