Helper library for the SCD30 CO2 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-scd30
To install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-scd30
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-scd30
import time import board import adafruit_scd30 i2c = board.I2C() # uses board.SCL and board.SDA scd = adafruit_scd30.SCD30(i2c) while True: # since the measurement interval is long (2+ seconds) we check for new data before reading # the values, to ensure current readings. if scd.data_available: print("Data Available!") print("CO2:", scd.CO2, "PPM") print("Temperature:", scd.temperature, "degrees C") print("Humidity:", scd.relative_humidity, "%%rH") print("") print("Waiting for new data...") print("") time.sleep(0.5)
