The aim of the study was to design a weather station dedicated for applications in the forestry. The device is thought to be used to measure temperature, pressure, humidity and sunlight and to record that data to the microSD memory card supplementing also the information on the time of measurement. The objective of the field part of the study was to gather accurate meteorological data from the interior of the forest to the geostatistical analysis, necessary for breeding purposes. Here we present the assumptions for technical equipment and describe the components of the device, including the systems of sensor and control. In the further stage of the study we performed the comparative test of the prototype with a professional weather station. The results show a very strong correlation between data form both devices, while the average error relative is at a very satisfactory level: temperature (0.15°C), relative humidity (–3.73%), pressure (–3.37 hPa) and light intensity (–0.82 klx). The project proved that it is possible to construct simple and economically grounded weather station. The total cost of presented prototype does not exceed 500 PLN (ca. 110 US$). We suggest to continue further research and development of the network of similar weather stations. It may allow to create a model of meteorological factors for bigger areas.
