+Script to read wind speed from a Davis Anémomètre-girouette Vantage Pro (6410)
+https://www.shapemaker.io/blog/wind-speed-measurements-with-anemometer-and-a-raspberry-pi
+
+Connexion:
+black (wind speed )     -> gpio21
+green (wind direction)  -> ADS1115 (module I2C) 
+Yellow                  -> 5v
+RED                     -> GND
+
+Attention:  The Raspberry Pi doesn't have analog inputs, so we need an analog-to-digital converter (ADC) to read the wind direction.
