· Can we reduce ventilation if CO 2 levels can be maintained below 1000 ppm? In some facilities, CO 2 monitoring is used to estimate occupancy, which in turn is used to reduce outdoor air intake if/when occupancy is low. This is known as demand control ventilation and in nonpandemic conditions can be a useful energysaving feature. However ...
In this paper we report on CO2 Meter, a doityourself carbon dioxide measuring device for the classroom. Part of the current measures for dealing with the SARSCoV2 pandemic is proper ventilation in indoor settings.

According to ASHRAE, the recommended CO2 level in buildings should be no more than 700 parts per million (ppm) above outdoor air. Since outdoor air is approximately 400ppm, indoor CO2 levels should be no more than 1,100 ppm. Note that this guideline is not designed to limit the amount of CO2, but rather to indicate that a proper level of clean air (1520 CFM/person) is being distributed in indoor spaces like classrooms…

window, hallway or another unoccupied classroom, the sensors will react to this source of fresh air and adjust the ventilation rate accordingly. CO 2 control is also an ideal way to control ventilation based on occupancy for large areas that may have intermittent and …
· These can optimize the air quality in rooms for more healthy and productive indoor living and working conditions. Figure 2: The increase of the concentration of CO2 (left axis) and aerosols (right axis) in a classroom over the duration of two lessons with a break.

With the implemented CO2 sensor we took the performance of those systems to a higher level since they are completely adapted to the received sensor measurements of the CO2. Our CO2 sensor allows you to define a different measuring range with an integrated DIP switch. Indoor CO2 sensor ANDRACO2 and duct CO2 sensor ANDKACO2 allow to set the measuring range from 0 to 2000 ppm (parts per million molecules) or from 0 to 5000 ppm (particles per million molecules). The output signal of both sensors ...

Indoor Air Quality in Classrooms and COVID19. April 12, 2021. The effect of poor indoor air quality in classrooms has been known for years. Chronic illnesses, reduced cognitive abilities, sleepiness, and increased absenteeism have all been attributed to poor IAQ specifically elevated CO2 levels. What''s more concerning today is the effect ...

Multiple Sensors Controlling a Single AHU: Control should be based on the highest CO 2 concentration measured in all spaces served by the air handler. This can be accomplished within the programming capabilities of most building control systems. Alternatively, transducers are available that can take in multiple inputs and pass through the highest value. Contact AirTest for recommended vendors ...
The Go Direct CO2 Gas Sensor measures gaseous carbon dioxide concentration levels, air temperature, and relative humidity. It can be used in a variety of biology experiments. It connects via Bluetooth® wireless technology or via USB to your device.
· School Classroom CO2 Monitoring. CO2 in School Classrooms. As reported in a Berkeley Labs study*, high classroom CO2 levels in can significantly impair decisionmaking performance. This can have a detrimental effect in schools where large amounts of students, ventilation issues and other causes elevate CO2 levels in classrooms and other areas.
