Enviro pHAT Plus environmental monitoring add-on for Raspberry Pi

Project description


Designed for environmental monitoring, Enviro+ lets you measure air quality (pollutant gases and particulates), temperature, pressure, humidity, light, and noise level. Learn more -

Build Status Coverage Status PyPi Package Python Versions


You're best using the "One-line" install method if you want all of the UART serial configuration for the PMS5003 particulate matter sensor to run automatically.

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.

:warning: This library now supports Python 3 only, Python 2 is EOL -

One-line (Installs from GitHub)

curl -sSL | bash

Note report issues with one-line installer here:

Or... Install and configure dependencies from GitHub:

  • git clone
  • cd enviroplus-python
  • sudo ./

Note Raspbian Lite users may first need to install git: sudo apt install git

Or... Install from PyPi and configure manually:

  • Run sudo python3 -m pip install enviroplus

Note this wont 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:

  • 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

And install additional dependencies:

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