This simple project uses the [CCS811 sensor breakout board](https://www.joy-it.net/en/products/SEN-CCS811V1) from Joy-it\nand the Arduino Uno to light an LED when the CO2 and TVOC levels\nsurpass a certain configurable threshold.\nThis signals that the room should be aerated.\n\n\n## Installation\n\nInstall the *Adafruit CCS811 Library* from the Arduino IDE Library Manager.\n\nOpen the ccs811-voc/ccs811-voc.ino file in the Arduino IDE and upload sketch.\n\n## Installation with Arduino-cli\n\n```bash\narduino-cli core install arduino:avr\narduino-cli compile --fqbn arduino:avr:uno ccs811-voc/ccs811-voc\narduino-cli upload -p /dev/ttyUSB0 --fqbn arduino:avr:uno ccs811-voc\n```\n\nReplace /dev/ttyUSB0 with whatever port your Arduino Uno is connected to.\n\n## Permission Denied Problem\n\nIf you get USB permission error in the Arduino IDE when uploading the sketch under Linux,\ntry the following:\n\n```bash\nsudo usermod -a -G dialout $USER\n\nsudo chmod a+rw /dev/ttyUSB0\n```\n\n## Components\n\n* [CCS811 sensor on Joy-it breakout board](https://www.joy-it.net/en/products/SEN-CCS811V1)\n* Arduino Uno\n* Led\n* Cables\n\n## License\n MIT License\n ","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftderflinger%2Farduino-aeration-indicator","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ftderflinger%2Farduino-aeration-indicator","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftderflinger%2Farduino-aeration-indicator/lists"}
