2.2 Installation
First, you need to install git on your Raspberry Pi, this is done with the following command:
Now you can download the required library for the sensor as follows:
Next you have to go to the directory of the library:
And with the next command install the library:
Finally, you need to acvate I2C by entering the following command in the console:
Go to Interfacing Opons and enable I2C
2.3 Program example
cd Adafruit_Python_BMP/
git clone https://github.com/bastienwirtz/Adafruit_Python_BMP.git
#!/usr/bin/python
# Author: Bastien Wirtz <[e-mail]>
# Can enable debug output by uncommenting:
#import logging
#logging.basicConfig(level=logging.DEBUG)
import Adafruit_BMP.BMP280 as BMP280
sensor = BMP280.BMP280()
print ('Temp = {0:0.2f} *C'.format(sensor.read_temperature()))
print ('Pressure = {0:0.2f} Pa'.format(sensor.read_pressure()))
print ('Altitude = {0:0.2f} m'.format(sensor.read_altitude()))
print ('Sealevel Pressure = {0:0.2f} Pa'.format(sensor.read_sealevel_pressure()))
sudo apt-get git
sudo python setup.py install
sudo raspi-config

3.2 Installation
In order to use the sensor with the Arduino, you must rst download the required library here. Unpack
the folder and save it in your Libraries folder.
This is usually located under Documents / Arduino / Libraries.
3.2 Program example
/***************************************************************************
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.
