This is a library for the Adafruit BME280 Humidity, Barometric Pressure + Temp sensor
|
||
|
|
|
||
|
|
Designed specifically to work with the Adafruit BME280 Breakout
|
||
|
|
* http://www.adafruit.com/products/2652
|
||
|
|
|
||
|
|
These sensors use I2C or SPI to communicate, up to 4 pins are required to interface
|
||
|
|
|
||
|
|
Use of this library also requires [Adafruit_Sensor](https://github.com/adafruit/Adafruit_Sensor)
|
||
|
|
to be installed on your local system.
|
||
|
|
|
||
|
|
Adafruit invests time and resources providing this open source code,
|
||
|
|
please support Adafruit and open-source hardware by purchasing
|
||
|
|
products from Adafruit!

To download. click the DOWNLOAD ZIP button, rename the uncompressed folder Adafruit_BME280.
|
||
|
|
Check that the Adafruit_BME280 folder contains Adafruit_BME280.cpp and Adafruit_BME280.h
|
||
|
|
|
||
|
|
Place the Adafruit_BME280 library folder your arduinosketchfolder/libraries/ folder.
|
||
|
|
You may need to create the libraries subfolder if its your first library. Restart the IDE.
