This is a frugal CO₂ sensor so most of the parts can be interchanged with similar ones. A detailed Bill of Materials with the exact components used in this version of the sensor is provided as ...

README Arduino-CO2-Sensor-Project Measuring CO2 in classrooms or other closed spaces allows us to check if the ventilation system is bringing in fresh air to replace the air with CO2 we are breathing ...

In this project we are going to show you that how to measure TVOC and CO2 using CCS811 air quality sensor with Arduino. Also, you will learn to interface CSS811 with Arduino using Adafruit library.

The prototype used an Arduino communicating over I2C to the sensor and an OLED screen, which he eventually put in a 3D printed case to carry around to sample CO2 concentration in various real ...

Two wireless CO2 sensor units based on Sensirion SCD40 sensor with M5Stack UNIT CO2 I2C sensor, and TeHyBug miniature CO2 sensor device.

The “maker” movement is receiving a lot of attention, especially in the field of education. In this context, we have created an Arduino–carbon dioxide fountain, devised to use digital tools, such as ...
