Description of ๐ŸŒฌ๏ธ Arduino-Compatible KEYESTUDIO CCS811 CO2 and VOC Gas Sensor for Enhanced Air Quality Monitoring

This sensor mainly uses the CCS811B chip. It is an ultra-low-power miniature digital gas sensor that can detect a wide range of volatile organic compounds (TVOCs), including equivalent carbon dioxide (eCO2) and metal oxide (MOX) levels. Equivalent carbon dioxide (eCO2) is measured in the range of 400 to 8192ppm (parts per million), and various volatile organic compounds (TVOC) ranges from 0 to 1187ppb (parts per billion). This sensor is very easy to set up and start working with. use it with an arduino to monitor the indoor or outdoor environment. This sensor module is compatible with the arduino microcontrollers. How to use: Search for "keyestudio wiki KS0457" in Google Chrome to get the wiki online tutorial for this product.

Extremely inaccurate, short shelf life

The device had a large error rate compared to a calibrated device, too inconsistent to set an offset in the code. Accuracy decreased over time and now after 6 months the device stopped working.

Pros
  • Delivery was very quick
Cons
  • Some flaws

Much better than the MQ series sensors

The use of this sensor is not entirely clear so I recommend reading the wiki in the product description. There is a library and sample code there. Plug in and done. This sensor is ridiculously better than the MQ sensors with small screens on them. The results update quickly and really make sense.

Pros
  • Easy setup
Cons
  • Problems

Great for reference but not for accuracy

This sensor was very easy to set up and get started. It has a 48-hour "burn-in" period, which means you'll have to let it run for 48 hours before it can remotely provide you with accurate data. Even if the sensor sends more accurate data, it is not pre-calibrated. So unless you're spending hundreds on a calibration kit, your readings are for reference only and not actual numbers to use.

Pros
  • Handy item
Cons
  • A few minor things

Burn through is essential

Good sensor, much better than MQ series sensors. Make sure it's on for 5 days, the specs say 48 hours. If you don't have a proper burn, you'll get an error message. The sensor has an MCU that does all the calibration. Make sure you burn it in a clean air environment, possibly outdoors.

Pros
  • This sensor is very easy to set up and get started. Use it with Arduino to monitor your internal or external environment.
Cons
  • High price

Ideal for reference but not for accuracy

This sensor was very easy to set up and get started. It has a 48-hour "burn-in" period, which means you'll have to let it run for 48 hours before it gives you accurate data remotely. Even if the sensor sends more accurate data, it is not pre-calibrated. So unless you're spending hundreds on a calibration kit, your readings are for reference only and not actual numbers to use.

Pros
  • This sensor mainly uses the CCS811B chip. This is a miniaturized ultra-low power digital gas sensor that can detect a wide range of volatile organic compounds (TVOCs), including equivalent concentrations of carbon dioxide (eCO2) and metal oxides (MOX).
Cons
  • Socket required

Global measurements

Everything seemed to work. I took it outside at about 40F outside and got back in before 70F, the CO2 sensor and TVOC showed dangerous levels. I'm using it now and it keeps showing wrong data compared to my other CO2 sensor (a bit more expensive). My recommendation is to spend more money to get reliable data. I'll run this for a few days to see if the CO2 data normalizes.

Pros
  • Carbon dioxide equivalent (eCO2) is measured in the range of 400 to 8192 parts per million (ppm) and the concentration of various volatile organic compounds (TVOC) is in the range of 0 to 1187 parts per billion (ppb).
Cons
  • boring packaging
