What's going on here?
The ESP8266 is a low-cost Wi-Fi microchip, with a full TCP/IP stack and microcontroller capability. We decided to have a go at integrating an ESP8266 with a DHT11 temperature/humidity sensor.
The ESP8266 logs onto the network wirelessly and pushes the temperature and humidity readings to our webserver. That data is stored and used to produce the Google line Chart above.
