A method for determining the moisture content of wood (1), comprising the operating steps of inserting the wood (1) between a first plate and a second plate (3) of a capacitor (4); applying a first signal to the first plate (2) of the capacitor (4) using the plate as a transmitting antenna; detecting on the second plate (3) a second signal induced by the first signal, using the second plate (3) as a receiving antenna, determining from the second induced signal detected, a third reference signal, obtaining a differential signal, determining the components of the differential in phase and in quadrature signals from the first signal, filtering the components of the differential in phase and in quadrature signals to obtain a filtered in phase component and a filtered in quadrature component, which are independent of the frequency of the first signal; and calculating the moisture content of wood (1) based on the value of the filtered in phase and in quadrature components of the differential signal
