http://aicra.ac.in NODEMCU | ESP8266 ESP8266 is a highly integrated chip designed for the needs of a new connected world . It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor. ESP8266 has powerful on-board processing and storage capabilities that allow it to be integrated with the sensors specific devices through its GPIOs with minimal development up-front and minimal loading during runtime.
