CJMCU: Air Quality Sensor Breakout Board CCS811

CCS811 Air Quality Breakout - Ultra-low Power Digital Gas Sensor for Monitoring Indoor Air Quality

What is it?

The CCS811 Air Quality Breakout is a digital gas sensor solution that senses a wide range of Total Volatile Organic Compounds (TVOCs), including equivalent carbon dioxide (eCO2) and metal oxide (MOX) levels for indoor air quality monitoring with a microcontroller unit (MCU), which includes an Analog-to-Digital converter (ADC), and an I²C interface.

Why did you make it?

The onboard CCS811 supports multiple measurement modes that have been optimized for low-power consumption during an active sensor measurement and idle mode extending battery life in portable applications. We have broken out each necessary pin on the CCS811.Note: Please be aware that the CCS811 datasheet recommends a burn-in of 48 hours and a run-in of 20 minutes (you must allow 20 minutes for the sensor to warm up and output valid data).

What makes it special?

• Integrated MCU,On-board processing,Standard digital interface
• Managing the sensor drive modes and measurements while detecting VOCs
• Provides indication of IAQ levels with no host intervention
• Extend battery life in portable applications
• No need for continuous monitoring in software, reduces host power/processing
• Stable and predictable behaviour regardless of air quality at power up
• Designed for high volume and reliability (> 5 year lifetime)
