BMP280 Digital Pressure and Temperature Sensor

The BMP280 is a combined pressure and temperature sensor.

This Device is available from ControlEverything.com [SKU: BMP280_I2CS]

https://www.controleverything.com/content/Barometer?sku=BMP280_I2CS

This Sample code can be used with Raspberry Pi, Arduino, Particle Photon, Beaglebone Black and Onion Omega.

Java

Download and install pi4j library on Raspberry pi. Steps to install pi4j are provided at:

http://pi4j.com/install.html

Download (or git pull) the code in pi.

Compile the java program.

$> pi4j BMP280.java

Run the java program.

$> pi4j BMP280

Python

Download and install smbus library on Raspberry pi. Steps to install smbus are provided at:

https://pypi.python.org/pypi/smbus-cffi/0.5.1

Download (or git pull) the code in pi. Run the program.

$> python BMP280.py

Arduino

Compile the c program.

$>gcc BMP280.c -o BMP280

Run the c program.

$>./BMP280

Onion Omega

Get Started and setting up the Onion Omega according to steps provided at :

https://wiki.onion.io/Get-Started

To install the Python module, run the following commands:

opkg update
opkg install python-light pyOnionI2C

Download (or git pull) the code in Onion Omega. Run the program.

$> python BMP280.py

#####The code output is the pressure in hPa and temperature reading in degree celsius and fahrenheit.
