The iSpindel is a digital hydrometer that lets you wirelessly see your home brew fermentation temperature and specific gravity. With built in WiFi, the iSpindel can connect to apps such as BrewFather to graph the progress of your ferment and be accessed anywhere in the world! The iSpindel can also be used to tie in with other hardware such as BrewPi / BrewPiLess in order to build fully automated fermentation temperature controllers.
