CCS811 Air Quality Sensor measures eCO2 and TVOC density. It uses AMS’s micro-hot plate tech, offering low power, fast heating, and compact size. Integrated ADCs/MCUs enable data collection/calculation via IIC. It supports concentration alarms (threshold triggers) and multiple modes (1s,10s,1min,250ms,sleep) optimized for low power—ideal for portable apps. Note: Its stretched IIC clock is incompatible with controllers like Raspberry Pi.

1. Example Code for Arduino-Get Baseline
Get the baseline value of the CCS811 Air Quality Sensor to enable quick air quality readings after warm-up. Without a baseline, the sensor takes longer to calibrate in polluted air.
2. Example Code for Arduino-Get Data
Read the concentration of carbon dioxide and TVOC using the CCS811 Air Quality Sensor. Input a baseline value for faster calibration or let the sensor auto-calibrate (longer process).
3. Example Code for Arduino-Concentration Alarm
Set up a concentration alarm where an interrupt is triggered when CO2 levels cross predefined thresholds (low→medium or medium→high). The current CO2 and TVOC values are printed on interrupt.
