Simple Weather Station with NodeMCU, Arduino and ThingSpeak

Build a weather station driven by a NodeMCU (esp8266) board written and Arduino and send the gathered data to ThingSpeak.

SWS (Simple Weather Station)
A Simple Weather Station controlled by a NodeMCU dev board writen in Arduino which reports data through ThingSpeak.

About the ESP8266

The ESP8266 is a low-cost Wi-Fi chip with full TCP/IP stack and MCU (microcontroller unit) capability produced by Shanghai-based Chinese manufacturer, Espressif Systems.
