ADAFRUIT CO2 SENSOR CCS811

Adafruit CCS811 Air Quality Sensor Breakout

This Adafruit CO2 Sensor CCS811 from AMS is a gas sensor that can detect a wide range of Volatile Organic Compounds (VOCs) and is intended for indoor air quality monitoring. When connected to your microcontroller (running our library code) it will return a Total Volatile Organic Compound (TVOC) reading and an equivalent carbon dioxide reading (eCO2) over I2C. There is also an onboard thermistor that can be used to calculate the local ******t temperature.

The CCS811 has a ‘standard’ hot-plate MOX sensor, as well as a small microcontroller that controls power to the plate, reads the ****og voltage, and provides an I2C interface to read from.

This part will measure eCO2 (equivalent calculated carbon-dioxide) concentration within a range of 400 to 8192 parts per million (ppm), and TVOC (Total Volatile Organic Compound) concentration within a range of 0 to 1187 parts per billion (ppb). According to the fact sheet it can detect Alcohols, Aldehydes, Ketones, Organic Acids, Amines, Aliphatic and Aromatic Hydrocarbons. We include a 10K NTC thermistor with matching balancing resistor which can be read by the CCS811 to calculate approximate temperature.
