Meet SmartyPans: an intelligent pan that tracks your nutrition and integrates with fitness devices to help you stay on the right track. It has a Bluetooth 4.2 chip, an Atmel M4 microcontroller, weight and temperature sensors, and a 800 mAh battery.
SmartyPans is pretty easy to use. Just tell the companion app what ingredients you are adding and let the pan do the measurement and tracking. Yet another interesting Indiegogo project.
