can co2 control sensor for classroom food

School Classroom CO2 Monitoring | Aretas Sensor Networks

· 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. It has also been shown that high school CO2 levels can negatively …

CO 2 Ventilation Control sensors for commercial buildings

· The EE80 and EE85 are dual beam sensors, where the sensor has an internal calibration method that does not rely on concentrations inside the building dropping to outside concentrations periodically. This sensor is ideal for applications that are operated 24/7 or that are operated in a way where the background method of self calibration may not work. There is a reference document to the …
