BME280 Temperature, Pressure, & Humidity Sensor

Suitable for measuring ambient temperature, barometric pressure, and humidity, the BME280 is a great indoor environmental sensor.

Installing

We'd recommend using this library with Raspberry Pi OS Bookworm or later. It requires Python ≥3.7.

Full install (recommended):

We've created an easy installation script that will install all pre-requisites and get you up and running with minimal efforts. To run it, fire up Terminal which you'll find in Menu -> Accessories -> Terminal on your Raspberry Pi desktop, as illustrated below:

In the new terminal window type the commands exactly as it appears below (check for typos) and follow the on-screen instructions:

git clone https://github.com/pimoroni/bme280-python
cd bme280-python
./install.sh

Note Libraries will be installed in the "pimoroni" virtual environment, you will need to activate it to run examples:

source ~/.virtualenvs/pimoroni/bin/activate

Development:

If you want to contribute, or like living on the edge of your seat by having the latest code, you can install the development version like so:

git clone https://github.com/pimoroni/bme280-python
cd bme280-python
./install.sh --unstable

Install stable library from PyPi and configure manually

• Set up a virtual environment: python3 -m venv --system-site-packages $HOME/.virtualenvs/pimoroni
• Switch to the virtual environment: source ~/.virtualenvs/pimoroni/bin/activate
• Install the library: pip install pimoroni-bme280

In some cases you may need to us sudo or install pip with: sudo apt install python3-pip.

This will not make any configuration changes, so you may also need to enable:

• i2c: sudo raspi-config nonint do_i2c 0

You can optionally run sudo raspi-config or the graphical Raspberry Pi Configuration UI to enable interfaces.
