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 ...
A simpler method could have been to put a CO2 sensor with a number display on the wall in the room, however there was a strong risk that this would be ignored or not seen due to its size. As the dashboard for the classroom was designed specifically to engage with children, it was felt that this risk would be significantly reduced. Another key advantage of the solution is that the CO2 data can ...

20160408· Using CO2 sensors for ventilation control can assist in these cases. However, other systems with audible and visual alarms, such as the ESRAD102 can be installed (Figure 2) warning workers and occupants of dangerous levels of CO2. The sensor is installed in the space with the CO2 source and an alarm indicator is placed outside.
The global warming controversy concerns the public debate over whether global warming is occurring, how much has occurred in modern times, what has caused it, what its effects will be, whether any action can or should be taken to curb it, and if so what that action should be. In the scientific literature, there is a strong consensus that global surface temperatures have increased in recent ...
