A computer-programmed thermostat and carbon monoxide detector device that, according to Wikipedia, is "Wi-Fi enabled, self learning, [and] programmable." In contrast with standard thermostats, which have to be manually controlled, Nest can integrate with other digital devices and auto-regulate in order to adapt to living routines and reduce energy consumption. As a device used in the home (and plausibly at businesses as well), Nest is named in reference to the word commonly used for the living structure of birds and other (often egg-bearing) animals.
