Digi-Key Weather Center

Positioned on the roof of Digi-Key's 600,000 square foot Product Distribution Center in Thief River Falls, Minnesota in July 2010, the Digi-Key Weather Center tracks the most dramatic of weather changes year-round. The Digi-Key Weather Center was developed to demonstrate connectivity to customers by using products available and supported by Digi-Key. This project is a collaborative effort by members of Digi-Key's Design Support Services team.

Weather Center Live Data

The table below is the collection of the data from the weather center structure and its sensor nodes. Each sensor node that has been developed is indicated by the Node name (Node_x) which may or may not have multiple sensors attached to it. In this example each node will transmit the type(s) of sensor(s) it is along with the corresponding data of that sensor. The data that is collected by each sensor is periodically transmitted to a database via a XML file. This XML file is then used to create the following table. Heat Index and Dew Point are calculated using measurements from the table and are not recorded by sensors. Although the Weather Center and the sensors mounted to it strive to bring you the most accurate information possible it does not follow the guidelines set forth by NOAA. This can result in differences between sensor readings on this website and readings on other websites and can also result in differences between similar sensor readings on this website. As these sensors are on the roof, temperatures during the summer months may read as higher than expected.
