CCS811 CO2 & TVOC Air Quality Sensor

CCS811 Digital TVOC & eCO2 Indoor Air Quality Sensor

The CCS811 is an ultra-low-power digital gas sensor solution integrating a metal oxide (MOX) gas sensor and an onboard microcontroller with ADC and I2C interface. It executes internal baseline correction algorithms to output equivalent CO2 and TVOC levels directly.

Specifications

• Equivalent CO2 (eCO2) Range: 400 to 29,206 ppm
• Total Volatile Organic Compounds (TVOC): 0 to 32,768 ppb
• Interface: I2C slave interface with interrupt event support
• Supply Voltage: 1.8V to 3.3V (breakout includes onboard 3.3V LDO)
• Low Power Modes: Sub-1.2 mW average power in 60s sampling mode
• Automatic baseline correction for long-term drift stability
