Finally, you must tell the software which COM port on your computer the Arduino Uno board is connected to.

Gravity analogue infrared CO2 sensor For Arduino is a high performance sensor that combines technology of mature infrared absorption gas detection with precision optical circuit design as well as sophisticated circuit design. I have been banging my head against the wall for days now and I have not found anything that can solve my issue on the internet either. The ZMOD4410 gas sensor module is an easily integrated firmware configurable architecture enabling multiple sensing solutions with a common hardware platform.The Gravity Analog Infrared CO2 Sensor for Arduino is a high-performance sensor that combines technology of mature infrared absorption gas detection with precision optical circuit design as well as sophisticated circuit design. Below is the step-by-step guide to complete the minimal connections needed to connect the Arduino and CO2 Sensor. By knowing the exact concentration of CO2, we can do somehing to reduce the CO2 and to protect our Earth. Since i never worked with similar sensors, i dont know if is even possible to do measurements in the outdoor (not placing the sensor inside the sewage drain), in a relative fast way (ie: not leaving the sensor for hours in the location). Anyway, I do not think that this correction would help, as the values continuously jump up to +-200 ppm.

There are two options for the sensor assembly: the easiest is using an Arduino Multifunction Shield (Shield), which already includes a 4-digit display, buzzer and buttons, making the assembly much easier. Perfect for environmental sensing, scientific experiments, air quality and ventilation studies and more.

b) Using a 1/8" endmill, cut just on the inside of the drawn rectangle as close to the line as possible. Once the CO2 concentration is high enough (voltage is lower than threshold), a digital signal (ON/OFF) will be released. By knowing the exact concentration of CO2(Carbon Dioxide), we can do something to reduce the CO2 and to protect our Earth.
