On the use of CO2 sensors in schools and other indoor ...

· A desirable scenario would be for a school to equip each classroom, plus the common rooms (lunchroom, library, etc.), with a CO2 sensor. The training needed by school staff to respond to the warnings by the CO2 sensor is negligible. For pupils, this can represent a learning experience about the use of technology and a way to feel proactive about the pandemic. The visual feedback from CO2 sensors can also increase window opening, as found by a study conducted in classrooms …

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
