Enviro+

Designed for environmental monitoring, Enviro+ lets you measure air quality (pollutant gases and particulates), temperature, pressure, humidity, light, and noise level. Learn more - https://shop.pimoroni.com/products/enviro-plus

Installing

Note The code in this repository supports both the Enviro+ and Enviro Mini boards. The Enviro Mini board does not have the Gas sensor or the breakout for the PM sensor.

⚠️ This library now supports Python 3 only, Python 2 is EOL - https://www.python.org/doc/sunset-python-2/

Install and configure dependencies from GitHub:

• git clone https://github.com/pimoroni/enviroplus-python
• cd enviroplus-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

Note Raspbian/Raspberry Pi OS Lite users may first need to install git: sudo apt install git

Or... Install from PyPi and configure manually:

• python3 -m venv --system-site-packages $HOME/.virtualenvs/pimoroni
• Run python3 -m pip install enviroplus

And install additional dependencies:

sudo apt install python3-numpy python3-smbus python3-pil python3-setuptools

Note this will not perform any of the required configuration changes on your Pi, you may additionally need to:

• Enable i2c: raspi-config nonint do_i2c 0
• Enable SPI: raspi-config nonint do_spi 0

And if you're using a PMS5003 sensor you will need to:

Bookworm

• Enable serial: raspi-config nonint do_serial_hw 0
• Disable serial terminal: raspi-config nonint do_serial_cons 1
• Add dtoverlay=pi3-miniuart-bt to your /boot/firmware/config.txt

Bullseye

• Enable serial: raspi-config nonint set_config_var enable_uart 1 /boot/config.txt
• Disable serial terminal: sudo raspi-config nonint do_serial 1
• Add dtoverlay=pi3-miniuart-bt to your /boot/config.txt
