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.

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 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)

Documentation

API documentation for this library can be found on Read the Docs.
