Cambridge CMOS Sensors : CCS811 – Ultra-Low Power Digital Gas Sensor for Monitoring Indoor Air Quality


The CCS811 is an ultra-low power digital gas sensor solution which integrates a metal oxide (MOX) gas sensor for monitoring indoor air quality (IAQ) including carbon monoxide (CO) and a wide range of volatile organic compounds (VOCs) with a microcontroller unit (MCU), a analog-to-digital converter (ADC), and an I2C interface.

It is based on Cambridge CMOS sensors’ unique micro-hotplate technology which enables a highly reliable solution for gas sensors, very fast cycle times and a significant reduction in average power consumption compared with traditional metal oxide gas sensors.
