However, when working effectively, a movement station can be a great resource for the whole class. It is important to monitor sensory strategies to ensure they are helping. Before using them it’s helpful to set goals so you can ...

Demand control ventilation (DCV) is required for spaces larger than 500 ft2 and with a design occupancy for ventilation of ≥ 25 people per 1000 ft2 of
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 the space using similar ...

2. CO2 can decrease productivity. In the office and classroom, elevated levels of CO2, in the range between 1,000ppm and 2,500ppm, have been found to decrease information utilisation, increase headaches, decrease performance, and increase rates of absenteeism (Satish et al 2012).
Theben CO 2 sensors monitor CO 2 levels in schools and classrooms, in offices and meeting rooms or in passive and lowenergy buildings. CO 2 sensors thereby make …
Problem behavior in the classroom is one of the most difficult aspects of a teacher''s job. It interrupts their lesson plans, tries their patience, interferes with the other children''s learning environment and leaves many teachers feeling overwhelmed, helpless, and out of control.
Inductive Sensors: Inductive proximity sensors are used for noncontact detection to find out the presence of metallic objects using electromagnetic field or a beam of electromagnetic can operate at higher speeds than mechanical switches and also seems more reliable because of its robustness. Capacitive Sensors: Capacitive proximity sensors can detect both metallic as well as …
· This sensor can operate at 0~50 °C temperature and 0~95% humidity. It has a measurement range of 0~2000 ppm, a lifespan higher than 5 years and an average current consumption lower than 10 mA. The MHZ19 has a V interface level and a PWM and UART output signal. Competing systems are more expensive than iAirCO 2 and they do not gather data in real time. This …
· 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 …

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 ...
· CO2 in School Classrooms. As reported in a Berkeley Labs study*, high classroom CO2 levels in can significantly impair decisionmaking performance. This can have a detrimental effect in schools where large amounts of students, ventilation issues and other causes elevate CO2 levels in classrooms and other areas.
