The relationship of wooden elements with humidity is of economic and technical importance. This is because the important structural behaviour of timber elements, especially their processing properties and mechanical behaviour, changes with the change in moisture content.  The determination of the amount of moisture in a wood material is now carried out with electric moisture meters in addition to the drying methods used in the past. This type of devices used in wood moisture measurement are generally imported from abroad, but they have only limited features due to their physical and technical structure deficiencies. In addition, they have high costs as they are purchased from abroad in foreign currency. It has been preferred to install the moisture measurement in wood on the Arduino system, which is frequently preferred in automation system designs and is also suitable for the production of economic solutions. The moisture measurement values obtained from different types of woods with the device we have created are compared with the moisture measurement values of the devices available in the market and shown on graphs
