What is Internet of Things (IoT) ?

The Internet of Things (IoT) refers to the ever-growing network of physical objects that feature an IP address for internet connectivity, and the communication that occurs between these objects and other Internet-enabled devices and systems. The Internet of Things can change the way citizens live, travel, and take care of each other. These developments are being supported by large corporations as well as startups.

What is ESP8266 ?

ESP8266 is a low-cost Wi-Fi microchip with full TCP/IP stack and microcontroller capability produced by Shanghai-based Chinese manufacturer, Espressif Systems. The first series of modules made with the ESP8266 is by Ai-Thinker an collectively referred to as "ESP-xx modules".

Novice ESP8266 developers are encouraged to consider NodeMCU, a larger ESP8266 Wi-Fi development boards, which includes the USB-to-UART bridge and a Micro-USB connector coupled with a 3.3 volt power regulator already built into the board
