| /*************************************************************************** | |
| This is a library for the BME280 humidity, temperature & pressure sensor | |
| This example shows how to take Sensor Events instead of direct readings | |
| Designed specifically to work with the Adafruit BME280 Breakout | |
| ----> http://www.adafruit.com/products/2652 | |
| These sensors use I2C or SPI to communicate, 2 or 4 pins are required | |
| to interface. | |
| Adafruit invests time and resources providing this open source code, | |
