Bastlíři sdílejte, hledá se meteosonda žáků 9.tř. ZŠ, která přistála někde v okolí Deštné u Blanska.
🛰Deváťáci z třebíčské Základní školy T. G. Masaryka navrhli, složili a naprogramovali stratosférickou sondu z komponentů našeho e-shopu. Sonda vylétla do výšky 33 kilometrů s cílem měřit teplotu a vlhkost, a vyfotit zakřivení země.🌍 #rpishop #rpishop_cz #RaspberryPi #sonda
