ESP8266 Esp-01 Serial WIFI Wireless Transceiver.

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 offload all Wi-Fi 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 up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry, and the entire solution, including the front-end module, is designed to occupy minimal PCB area.

ESP8266 Esp-01 Serial WIFI Wireless Transceiver Warning:

This module requires a 3.3 volt supply for VCC and 3.3V logic. It is not 5V tolerant. Connecting RX or TX on 5V Arduino will destroy this module. You must use a logic level converter or a 3.3V Arduino 3.3V supply on the Arduino Uno has an inadequate current capability to power this module. You must provide a separate, higher 3.3V supply(about 300mA or higher)
