CircuitPython library for CCS811 air quality sensor.

Project description

Adafruit CircuitPython CCS811 Library

Documentation Status Discord Build Status

CircuitPython driver for the CCS811 air quality sensor.


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 locally from PyPI. To install for current user:

pip3 install adafruit-circuitpython-ccs811

To install system-wide (this may be required in some cases):

sudo pip3 install adafruit-circuitpython-ccs811

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-ccs811

Usage Notes

See the guide for wiring and installation instructions.

Of course, you must import the library to use it:

import busio
import adafruit_ccs811

Next, initialize the I2C bus object.

from board import *
i2c = board.I2C()   # uses board.SCL and board.SDA

Once you have created the I2C interface object, you can use it to instantiate the CCS811 object

ccs =  adafruit_ccs811.CCS811(i2c)

Reading Sensor

To read the gas sensor simply read the attributes:

print("CO2: ", ccs.eco2, " TVOC:", ccs.tvoc)


Contributions are welcome! Please read our Code of Conduct before contributing to help this project stay welcoming.
