Carbon Dioxide (CO HVAC Basics - Honeywell

Do not confuse carbon dioxide (CO2) with carbon monoxide (CO), a highly toxic gas that is also a byproduct of combustion in furnaces, fireplaces and automobiles. Carbon monoxide (CO) can be harmful, even at very low levels (25 to 50 ppm). CO2 as an IAQ Indicator Claims that CO2 sensors are indoor air quality (IAQ) sensors are inaccurate. CO2 levels are one piece of the undefined indoor air ...

atmospheric carbon dioxide sensing with an Arduino ...

2018-06-18· The sensor can be calibrated in atmospheric CO2 conditions at the push of a button. I have reservations about this one-point calibration but “you pays yer money…”, as my dad used to say. The Nano is sitting on a screw terminal shield with mount holes for easy connections ($4 well spent for making secure, non-permanent connections to the Arduino). On the laptop screen you can see data ...

Gas Sensor Applications |

A sensor that is ideal for measuring indoor CO2 levels for indoor air quality will not work to measure concentrations used in fire suppression testing. One OEM might want I2C protocols, while another individual prefers UART. Some applications require the use of a sampling sensor instead of diffusion.

CO2 Sensor Arduino Compatible - RobotShop

The CO2 Sensor Arduino Compatible is the first CO2 sensor in OSHW market. The output voltage of the module falls as the concentration of the CO2 increases. The potentiometer onboard is designed to set the threshold of voltage. As long as the CO2 concentration is high enough (voltage is lower than threshold), a digital signal (ON/OFF) will be released. It has MG-811 sensor module onboard which ...
