REGISTER EDUCATION FORUM / BIOMETRICS / SPARKFUN AIR QUALITY BREAKOUT - CCS811 SparkFun Air Quality Breakout - CCS811 SEN-14193 4 DESCRIPTION FEATURES DOCUMENTS 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. VOCs are often categorized as pollutants and/or sensory irritants and can come from a variety of sources like construction materials (paint, carpet, etc.), machines (copiers, processors, etc.) and even people (breathing, smoking, etc.). This breakout is intended for indoor air quality monitoring in personal devices such as watches and phones, but we've put it on a breakout board so you can use it as a regular I2C device. 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 as well as additional pins to add your own NTC Thermistor to determine the temperature of the CCS811's surroundings, which can be used to help compensate the readings. 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). images are CC BY 2.0 SHARE GET STARTED WITH THE CCS811 BREAKOUT GUIDE Previous Versions Tags BIOMETRICS BREAKOUT CCS811 CO2 WEATHER SparkFun Air Quality Breakout - CCS811 Product Help and Resources TUTORIALS VIDEOS SKILLS NEEDED CCS811 Air Quality Breakout Hookup Guide APRIL 27, 2017 CCS811/BME280 (Qwiic) Environmental Combo Breakout Hookup Guide SEPTEMBER 8, 2017 This tutorial shows you how to get data from a CCS811 breakout board with the I2C interface.

Fantastic board about 7 months ago by Member #570629 verified purchaser Really simple to use, remarkably accurate, and surprisingly sophisticated. Just what this project needed! very usefull about 6 months ago by Member #881539 verified purchaser I had to unsolder the pull up resistors to make it working on an AT91 Sam9G25 plateform. No works flawlessly M-Short replied on November 7, 2017: For future reference most of our boards (including this one) have the pullup resistors soldered on so that they can be used as is, but also have jumpers on the board where you can cut the trace to disconnect them which should be easier than desoldering. Very good for proof of concept demo about a month ago by Member #1239279 verified purchaser This product is easy to use, has great docs, and is very reliable. Great for student projects Easy to implement but values go out of control on continuous use about a month ago by dafoink verified purchaser Ok. it is pretty easy to use. and the library is very easy. But, after a few hours of continuous use, the values go crazy. I also added temp/humidity compensation. but still, after an hour or two, the results go off the charts. Anyone else have an idea on how to handle this? Or is there a problem with the actual device? CF replied on January 2, 2018: It sounds like you may have a connection issue or a bad unit.
