WHAT IS COR?
COR is a defense against a major problem in the lives of students and teachers:
the worsening of air quality in classrooms.
The air in classrooms is in fact too often neglected and not considered as a problem although the accumulation of carbon dioxide leads to disastrous consequences for students.
This problem prompted us to come up with a solution which is why we have created a low cost and easily replicable system capable of detecting CO2 and signaling its excess in order to guarantee optimal air quality.
HOW DOES COR WORK?
The system is based on ARDUINO (look: https://www.arduino.cc/ ) and on other components including:
A buzzer wich will warn the class that the limit threshold has been exceeded through a sound emission so as to be able to open the windows and facilitate the exchange of air
An LCD screen which allows the practical consultation of the current and initial CO2 values (so as to easily view the increase of the CO2 levels)
The cjmcu-811 (CCS811) sensor which is the real brain of the system since it performs the actual measurements.
This sensor also measures VOCs and TOCs, very common compounds especially in laboratories, the sensor would therefore be easily adaptable to school laboratories with a simple change of a code string.

HOW TO MAKE IT:
The system is easily replicable since we used Arduino thus minimizing the necessary soldering and used a 3D printer for the enclosures.
