What is the esp8266webserver library?

The ESP8266WebServer library allows you run an ESP8266 as a basic webserver and access point. This can process data received from a remote sensor over Wi-Fi without connecting the devices to a network or router. For this tutorial I’m using two NodeMCU boards from eBay but you can do this with any ESP8266 based board.
