CCS811 Gas Sensor Solution

Ultra-Low Power Digital Gas Sensor for Monitoring Indoor Air Quality

The CCS811 is an ultra-low power digital gas sensor solution that integrates a metal oxide (MOX) gas sensor for monitoring indoor air quality. This includes a wide range of Volatile Organic Compounds (VOCs), a microcontroller unit(MCU), and Analog-to-Digital Converter (ADC), and an I2C interface.

The AS-MLV-P2 high-performance sensor component is highly sensitive to volatile organic compounds for superior monitoring of indoor air quality.
