ADVANTAGES OF USING CARBON DIOXIDE SENSORS IN CLASSROOMS ...

2012-10-24· Let us take, for example, a classroom, where close to 40 persons or more may gather at a time, each releasing between 20 and 25 liters of carbon dioxide per hour through respiration alone; this usually winds up with poor air quality being the end result which can lead to the “sick building syndrome” phenomenon. The introduction of carbon dioxide sensors in classrooms has proven to help in ...

Demand-Controlled Ventilation (DCV) - SVACH

DCV sensors most commonly measure carbon dioxide (CO2) and/or relative humidity. Typically, the ventilation system withdraws air from “damp or humid” rooms (bathrooms, kitchens, laundry, work areas) and supplies air to “dry” rooms (offices, living rooms, bedrooms). Occupancy sensors, like those used for lighting systems, may also control ventilation systems. Occupancy sensors are a ...
