CO2 & TVOC Measurement using CCS811 Air Quality Gas Sensor & Arduino

whats the difference between this CCS811 Air Quality Gas Sensor and a bme680?

great video! can u explain why the sensor can detect over 30,000 ppm? The datasheet tells us that CCS811just detect over 8,000 ppm.

Hello, a nice and simple project. Please tell me how you can add 5 more pieces of ws2812 led to this project so that they would change color from green - yellow to red as CO2 ppm increases . That would be really cool. How to do it? Is it very difficult?

I know it's quite old already, but there are few things you forgot to mention/implement.
First, the sensor has its burn-in period, during which the measures are not accurate. For some sensors it may take about 1 week to stabilize the reading.
Second, this sensor needs temperature and humidity to compensate the readings. Both the values affect CO2 and TVOC otherwise.

I saw you suggested to change I2C address in library, but this can be done by passing the address when initializing library.

Is there any way this sensor can be used outdoors?

I have an LCD 1602 I2C. Do I have to change the code so it would work?

Hello. I bought a keyestudio CCS811 sensor, but I'm having tons of trouble with the second code trying to connect it to the OLED, could you give a hand please? :)

Hi. I want to ask. Why on serial monitor. It show ccs8111 test ERROR!

How can I change the address in the library?

Hi. I want to ask. Ccs811 can measure CO2 and TVOCS from human exhalation breathing?

Great video

Nice video

Super

Awesome tutorial Thanks to How To Electronics team!!
