The Story
The CJMCU-811 module features the ultra-low-power CCS811 digital gas sensor, designed for indoor air quality monitoring. It detects carbon monoxide (CO), carbon dioxide (eCO2), and a wide range of volatile organic compounds (VOCs) with high sensitivity and fast response. The module communicates via I2C interface, making it easy to integrate with microcontrollers for smart home and environmental sensing projects.
