This is a library for the BMP280 humidity, temperature & pressure sensor
|
|
|
|
Designed specifically to work with the Adafruit BMEP280 Breakout
|
|
----> http://www.adafruit.com/products/2651
|
|
|
|
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,
