CircuitPython library for CCS811 air quality sensor.
Project description
Adafruit CircuitPython CCS811 Library
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-ccs811To install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-ccs811To install in a virtual environment in your current project:
mkdir project-name && cd project-name
python3 -m venv .venv
source .venv/bin/activate
pip3 install adafruit-circuitpython-ccs811Usage Notes
See the guide for wiring and installation instructions.
Of course, you must import the library to use it:
import busio
import adafruit_ccs811Next, initialize the I2C bus object.
from board import *
i2c = board.I2C() # uses board.SCL and board.SDAOnce 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.
