ESP8266 is a highly integrated chip designed for the needs of a new connected world. It offers a complete and selfcontained WiFi networking solution allowing it to either host the application or to offload all WiFi networking functions from another application processor.

ESP8266 has powerful onboard processing and storage capabilities that allow it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development upfront and minimal loading during runtime. Its high degree of onchip integration allows for minimal external circuitry and the entire solution including frontend module is designed to occupy minimal PCB area.
