My brother-in-law Chris wants to build a wood-fired pizza oven in his backyard. Chris is an aspiring pizza chef at night, but a process engineer by day. Although his pizza oven will be built from age old sand and clay, veins of chromium and aluminum will be running through the walls. These veins are thermocouples, a precision temperature measurement sensor. Four of these thermocouples meet back at the PiMometer, a custom-made circuit board and Raspberry Pi combo. Temperatures from throughout the oven will be displayed on a continuously updating webpage viewable from any smartphone or PC.
