mutevent mute button with CO2 warning |

Jun 18, 2021· VOC sensors are cheaper and can output "equivalent CO2", essentially just multiplying the measured volatile organic compounds by the average proportion of exhaled VOCs to CO2. These could be confused by your furniture, a strong drink and many other sources. They just make you vent more often then, so no issue. Packaging is small enough for any ...

Indoor and outdoor air has between 400ppm and 2,000ppm CO2 by volume. This means that for projects from measuring indoor air quality to measuring atmospheric CO2, a 01% (010,000ppm) CO2 sensor is your best solution. For applications like CO2 alarms in restaurants, breweries, or around stored CO2 tanks, a 5% CO2 sensor is used.
