Seven Great Experiments Using the Wireless CO2 Sensor ...

· Here’s a quick look at some of the cool things you can do with the new Wireless CO2 Sensor! 1. Monitor Air Quality. An engaging way to introduce students to the sensor is to use the “closed” environment that you already have access to – your classroom or lab. This is also a great opportunity to use the data logging capabilities of the ...

Indoor Air Quality in Classrooms and COVID19 |

And OSHA and the US Green Building Council have even tighter indoor CO2 recommendations. Following on the research already conducted on indoor air quality additional studies are now being formed like that at the University of Colorado , focusing on how to control the transmission of airborne infectious diseases indoors, specifically in the classroom or university setting.

Arduino CO2 Meter Measure CO2 using Arduino | Circuit Digest

· MQ135 Gas Sensor is an air quality sensor for detecting a wide range of gases, including NH3, NOx, alcohol, benzene, smoke, and CO2. MQ135 sensor can either purchased as a module or just as a sensor alone. In this project, we are using an MQ135 sensor module to measure CO2 concentration in PPM. The circuit diagram for the MQ135 board is given below:

DemandControlled Ventilation (DCV) SVACH

Occupancy sensors are a common strategy for bathroom ventilation. Human respiration and combustion appliances generate CO2, which is a minor pollutant. DCV controls use CO2 as a surrogate. The term surrogate means that ventilation controls use CO2 concentration to control the concentration of other occupantrelated pollutants. Designers assume that controlling CO2 controls all occupancy …

Suggested CO Control Sequence Of Operation

offices can generally be controlled with one sensor in the central space (up to 5000 sq ft). In office building floor plates divided up into separate suites, at least one sensor per suite is recommended. Sensor Placement: Sensors should be placed so that they can take a representative sample of CO 2 concentrations in each major occupied zone. Sensors can be placed in the space using similar ...

How does an NDIR CO2 Sensor Work? |

NDIR is an industry term for " nondispersive infrared ", and is the most common type of sensor used to measure carbon dioxide, or CO2. An infrared (IR) lamp directs waves of light through a tube filled with a sample of air toward an optical filter in front of an IR light detector. The IR light detector measures the amount of IR light that passes ...
