Project Name : Solar Powered WiFi Weather Station V2.31
Features: temperature, dewpoint, dewpoint spread, heat index, humidity, absolute pressure, relative pressure, battery status and
the famous Zambretti Forecaster (multi lingual)
Authors: Keith Hungerford, Debasish Dutta and Marc Stähli
Website : www.opengreenenergy.com
Main microcontroller (ESP8266) and BME280 both sleep between measurements
BME280 is used in single shot mode ("forced mode")
CODE: https://github.com/3KUdelta/Solar_WiFi_Weather_Station
INSTRUCTIONS & HARDWARE: https://www.instructables.com/id/Solar-Powered-WiFi-Weather-Station-V20/
3D FILES: https://www.thingiverse.com/thing:3551386
CREDITS:
Inspiration and code fragments of Dewpoint and Heatindex calculations are taken from:

CREDITS for Adafruit libraries:
This is a library for the BME280 humidity, temperature & pressure sensor
Designed specifically to work with the Adafruit BME280 Breakout
----> http://www.adafruit.com/products/2650
These sensors use I2C or SPI to communicate, 2 or 4 pins are required
to interface. The device's I2C address is either 0x76 or 0x77.

major update on 15/05/2019
-added Zambretti Forecster
-added translation feature
-added English language
-added German language
updated on 03/06/2019
-added Dewpoint Spread
-minor code corrections
last updated 28/06/19

//// Features : //////////////////////////////////////////////////////////////////////////////////////////////////////
// 1. Connect to Wi-Fi, and upload the data to either Blynk App and/or Thingspeak
// 2. Monitoring Weather parameters like Temperature, Pressure abs, Pressure MSL and Humidity.
// 3. Extra Ports to add more Weather Sensors like UV Index, Light and Rain Guage etc.
// 4. Remote Battery Status Monitoring
// 5. Using Sleep mode to reduce the energy consumed
