Adafruit has unveiled a new air quality sensor breakout board they have created in the form of the Adafruit CCS811 which is capable of measuring both VOC and eCO2.
The tiny air quality sensor is now available to purchase directly from the Adafruit online store and is priced at $19.95. Its been designed to make easy work of adding air quality monitoring to any project.
Adafruit explains more about what you can expect from this tiny air quality sensor breakout board they have created.
This sensor 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 ambient temperature.
The CCS811 has a ‘standard’ hot-plate MOX sensor, as well as a small microcontroller that controls power to the plate, reads the analog 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.
