CircuitPython driver from BMP280 Temperature and Barometic Pressure sensor
Installation and Dependencies¶
This driver depends on:
Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.
Installing from PyPI¶
On supported GNU/Linux systems like the Raspberry Pi, you can install the driver from PyPI. To install for the current user:
pip3 install adafruit-circuitpython-bmp280
To install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-bmp280
To install in a virtual environment in your current project:
mkdir project-name && cd project-name python3 -m venv .env source .env/bin/activate pip3 install adafruit-circuitpython-bmp280
