can co2 control sensor for classroom environment

How can CO2 sensing help overcome COVID19?

· Each of these loggers is designed with a CO 2 monitoring sensor that can measure a range from 0 to 9999 ppm. By placing these loggers around a room and setting an alert limit on the max ppm, users can quickly identify when a room is reaching a limit that is unsafe for its occupants. Understanding how CO 2 concentration affects the potential for accelerated transmission of COVID …

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.

Control of CO2 in a naturally ventilated classroom ...

· At least one classroom should have a CO 2 sensor for continuous monitoring and recording. There are several suitable units that could allow realtime monitoring or trend history with reporting. A visual, ‘traffic light’ type sensor could be used which would alert the teacher to provide more ventilation when 1500 ppm is exceeded.

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

· In environments like schools, monitoring CO2 has added benefits in avoiding increased CO2 levels, which are known to create tiredness in pupils and reduce learning abilities, and have been reported previously as rather prevalent among Swiss classrooms. The benefit of CO2 sensors in schools will thus outlive the pandemic and provide a better learning environment in the long term.

CO2 Dashboards for Ventilation Monitoring in Schools

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 ...

Why Monitor CO2 in Classrooms?

The most obvious method to ensure that a room is properly ventilated, which aids in maintaining a highlevel 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 of the air within that …
