ams CCS811 Ultra-Low Power Digital Gas Sensor Datasheet
The ams CCS811 is an ultra-low power digital gas sensor solution designed for monitoring indoor air quality. It integrates a metal oxide (MOX) gas sensor to detect Volatile Organic Compounds (VOCs) with a microcontroller unit (MCU) and an I²C interface. The device supports intelligent algorithms to output equivalent total VOC (eTVOC) and equivalent CO2 (eCO2) values.

What is the minimum supply voltage for the CCS811?
The minimum supply voltage VDD is 1.8V and should not drop below this value for reliable device operation.
From: ams CCS811 Ultra-Low Power Digital Gas Sensor Datasheet
How long should the sensor run before accurate readings are generated?
After writing to MEAS_MODE to configure the sensor in mode 1-4, run CCS811 for 20 minutes before accurate readings are generated.

What communication interface does the CCS811 use?
The sensor uses a standard I²C digital interface for data transfer.
How many measurement modes are available and what do they do?
The CCS811 provides five modes (0‑4); mode 0 is idle, mode 1 measures every second, mode 2 every 10 s, mode 3 every 60 s, and mode 4 supplies raw data every 250 ms.
