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
|
|
from Adafruit!
