+/***************************************************************************
+  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.
+
+  Adafruit invests time and resources providing this open source code,
+  please support Adafruit andopen-source hardware by purchasing products
