Devices known as weather sensors served the purpose of detecting the atmospheric conditions and weather patterns of a given planet. While residing on the Bogano planet, the Jedi Master Eno Cordova constructed a weather sensor with the intention of determining the appropriate times to don a sweater during his explorations. However, Cordova's device instead registered electromagnetic radiation present within Bogano's winds. He posited that this phenomenon contributed to the ancient Zeffonian species's decision to erect a vault on that particular world.
