New CO2 BACnet Sensor - Clarkson Controls

We have developed a range of intelligent temperature, humidity and CO 2 sensors which communicate using the open source BACnet protocol. Sensors also have 2-0/10v analogue outputs (10mA) which by using your favourite BACnet master controller you can write your own software logic to suit the application, using the items selected from the BACnet object list.

Examining the Value of C02 Sensors in Green Buildings ...

· When CO2 sensors are used with demand control ventilation (DCV) systems, the amount of fresh-air ventilation is controlled based on how many people are actually in a space at any given time. When CO2 levels rise with increased occupancy, more fresh air is introduced by opening dampers. CO2 levels fall as people leave, so the dampers close to reduce the amount of air that must be heated or ...

Why Monitor CO2 in Classrooms? -

The most obvious method to ensure that a room is properly ventilated, which aids in maintaining a high-level of indoor air quality, is to monitor Carbon Dioxide (CO2) levels within the classroom. Every time you exhale, you release CO2 into the air. Therefore, the CO2 level lets you determine if the room is being properly ventilated with fresh outside air; thereby, helping you gauge the quality ...

Suggested CO Control Sequence Of Operation

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 ...
