CCS811 Indoor air quality monitoring CO+VOC gas sensor
The CCS811 Air Quality Sensor can measure the eCO(Carbon monoxide) and VOC(Volatile Organic Compounds) density. It can be widely used in many applications, such as air quality detection, air purifiers, ventilation system etc. This air quality sensor uses AMS's unique micro-hot plate technology. Internally integrated ADCs and MCUs allow data to be collected, calculated and returned via I2C. This module supports a concentration alarm, which is triggered when the concentration exceeds the user-set threshold.
The CCS811 air quality sensor supports multiple modes, such as detect in every second, in every 10s, in every one minute, in every 250ms and sleep mode. These modes are optimized for low power consumption during the sensor measurement, so the CCS811 is also suitable for portable applications.
NOTE: The chip has stretched the clock in I2C. So, it is not compatible with some controllers, such as Raspberry Pi.
