Indoor Carbon Dioxide Levels and Your Health | IndoorDoctor

Though carbon dioxide is not toxic itself, the amount found in the indoor environment is used as an indicator for human comfort. Since carbon dioxide is an unavoidable, predictable, and easily measured product of human occupancy, it is used as a marker for whether pollutants introduced from humans or other sources in the building are likely to ...

CO2 Sensor Measurement Range, Accuracy and Precision ...

Apr 22, 2020· Apr 22, 2020· The VOC reading is a bit misleading because the CO2 levels are included, so if they are subtracted (and note CO2 is in ppm, while tVOC is in ppb), VOCs don’t seem to be cause for concern. So, while the Foobot provides convenience and calibrated sensors and can measure particulate matter, it doesn’t offer a number of readings I could obtain ...

May 23, 2019· May 23, 2019· In addition to getting the “big picture” of your indoor air quality, an indoor air quality monitor can be set up to provide threshold alerts. If, for example, the outside air has a CO2 level of 400 ppm, you could set up your monitoring equipment to alert you when indoor levels reach 950, and when the air has reached critical point at 1100 ppm.

Why are the CO2 Levels Different Between 2 Devices ...

The TIM10 CO2 meter has an accuracy of ±50ppm and ±5%, so at a reading of 846ppm, the actual amount of CO2 could be between 796-896ppm (50ppm > 5% of 846ppm). Since the 2 sensors accuracy ratings overlap between 796ppm and 808ppm, you can say they are both correct within their rated accuracy. While this sounds like theory instead of science ...

Carbon Dioxide (CO HVAC Basics - Honeywell

Claims that CO2 sensors are indoor air quality (IAQ) sensors are inaccurate. CO2 levels are one piece of the undefined indoor air quality equation. Low CO2 levels do not indicate good air quality while high CO2 levels do not mean that air is harmful. So CO2 sensors should be presented and sold as sensors of CO2 levels that provide information ...

Identifying poorly ventilated areas and using CO2 monitors

How to use a CO2 monitor. CO2 levels vary within an indoor space. It’s best to place CO2 monitors at head height and away from windows, doors, or air supply openings. Monitors should also be positioned at least 50cm away from people as their exhaled breath contains CO2. If your monitors are too close they may give a misleadingly high reading.
