CircuitPython driver from BMP280 Temperature and Barometic Pressure sensor
Installation and Dependencies
This driver depends on:
-
Adafruit CircuitPython <https://github.com/adafruit/circuitpython>
_ -
Bus Device <https://github.com/adafruit/Adafruit_CircuitPython_BusDevice>
_
Please ensure all dependencies are available on the CircuitPython filesystem.
This is easily achieved by downloading
the Adafruit library and driver bundle <https://github.com/adafruit/Adafruit_CircuitPython_Bundle>
_.
Installing from PyPI
On supported GNU/Linux systems like the Raspberry Pi, you can install the driver
from PyPI <https://pypi.org/project/adafruit-circuitpython-bmp280/>
_. To install
for the current user:
.. code-block:: shell
pip3 install adafruit-circuitpython-bmp280
To install system-wide (this may be required in some cases):
.. code-block:: shell
sudo pip3 install adafruit-circuitpython-bmp280
To install in a virtual environment in your current project:
.. code-block:: shell
mkdir project-name && cd project-name
python3 -m venv .env
source .env/bin/activate
pip3 install adafruit-circuitpython-bmp280
Usage Example
.. code-block:: python
import time
import board
# import digitalio # For use with SPI
import busio
import adafruit_bmp280
# Create library object using our Bus I2C port
i2c = busio.I2C(board.SCL, board.SDA)
bmp280 = adafruit_bmp280.Adafruit_BMP280_I2C(i2c)
# OR create library object using our Bus SPI port
# spi = busio.SPI(board.SCK, board.MOSI, board.MISO)
# bmp_cs = digitalio.DigitalInOut(board.D10)
# bmp280 = adafruit_bmp280.Adafruit_BMP280_SPI(spi, bmp_cs)
# change this to match the location's pressure (hPa) at sea level
bmp280.sea_level_pressure = 1013.25
while True:
print("\nTemperature: %0.1f C" % bmp280.temperature)
print("Pressure: %0.1f hPa" % bmp280.pressure)
print("Altitude = %0.2f meters" % bmp280.altitude)
time.sleep(2)
