Adafruit BME280

/*The Adafruit BME280 is a digital temperature and humidity sensor that communicates over I2C or SPI. Here's an example code in Arduino that reads the temperature, pressure, and humidity from the sensor using the I2C interface:

Note: This code assumes that the Adafruit BME280 sensor is connected to the I2C bus of the Arduino board with the I2C address 0x76. If you're using a different I2C address or interface, you'll need to modify the bme initialization accordingly.
