Abrégé
Disclosed is a device with a data transferring unit and a method for measuring moisture content of a wood material. Knots and other imperfections in a wood material causes problems in moisture content measurements. Also, more accurate data relating to the moisture of the material is needed during the time of storing, transporting and building. A device for measuring moisture in wood material includes a body part arrangeable on a surface of the wood material, measuring unit being functionally connected to the body part, wherein the measuring unit includes at least a first pair of electrodes and a second pair of electrodes to be inserted in the wood material for investigating, and wherein a measuring depth of the first pair and the second pair is arranged to differ for providing impedance data from a first depth and/or a second depth of the wood material.

Abrégé
The invention relates generally to a device with data trans- ferring means and a method for measuring moisture content of a wood material. Knots and other imperfections in a wood material causes problems in moisture content measurements. Also, more accurate data relating to the moisture of the material is needed during the time of storing, transporting and building. A device for measuring moisture in wood material according to the present invention comprises a body part arrangeable on a surface of the wood material, measuring means being functionally connected to the body part, wherein the measuring means comprises at least a first pair of electrodes and a second pair of electrodes to be inserted in the wood material for investigating, and wherein a measuring depth of the first pair and the second pair is arranged to differ for providing impedance data from a first depth and/or a second depth of the wood material.

Abrégé
The invention relates to a device, system and method for measuring moisture in building structures. A tubular body part (100) may be embedded in a material during its casting. Hole(s) (106) provided in the body part (100) lets moisture inside a space separated by the body part (100). Measuring element including electronics (102) and a sensor (104) functionally connected to the body part (100) is used to measure the separated space 108. With a reading device (234), the results may then be read from above surface due to a provided wireless link between the measuring element (102) and (104) and the reading device (234).
