can co2 control sensor for classroom equipment

Carbon Dioxide (CO HVAC Basics Honeywell

Proportional control uses sensor models that allow the installer to scale the output to corre spond with the control range desired. For example, a 2 to 10 Vdc signal can be adjusted to match a CO2 level differential range of 400 to 1,000 ppm. Proportional ventilation control is ideal in spaces with highly variable and unpredictable occupancies such as bars, restaurants, conference rooms ...

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

Carbon dioxide dosing in commercial greenhouses – gas ...

· To control the CO2 level in the greenhouse, an NDIR sensor is typically used. The target set point will generally be 800 ppm of CO2. When the sensor detects a reduced CO2 level in the greenhouse it will activate the CO2 dosing system. When the required CO2 level has been achieved, the measured value will increase, and the control system will shut off the CO2 supply.
