The UDA innovates in the manufacture of CO2 meters
Use of a mask, social distancing and ventilation are the main requirements for this return to face-to-face classes. However, at the University of Azuay a biosafety protocol has been managed, which largely stands out due to the implementation of carbon dioxide (CO2) meters.
The teams have been developed entirely by UDA teachers and students. With these devices it is sought to obtain control of three parameters around the quality of oxygen: CO2, temperature and humidity.
In the creation of these devices, students of Object Design have actively collaborated, specifically in the production of housings, and Electronic Engineering for the coupling of parts, most of which were acquired abroad. In addition, it had the support of the Department of Information Technology.
"The main characteristic of our equipment, and unlike others in the market, is the application that we have developed, where all measurements are reported in a database to later make a complete analysis", said Andrés López, Dean of the Faculty of Science and Technology.
Being a project that lasted about five months, various tests of the equipment were carried out in the university classrooms with various types of capacity.
To start these monitors you must wait around ten minutes. According to international regulations, the appropriate measurements outdoors should mark around 400 parts per million (PPM) and indoors between 500 and 800 PPM.
Favio Bohorque, Coordinator of Occupational Safety and Health of the Faculty of Science and Technology, explained the meter models developed:
“There are two types of models and they are used in a hierarchical way. The first is a catalytic sensor, which has a regular reliability due to its stabilization time that oscillates the ten minutes. When one of the indicators shows a peak, it leads to our second meter, which is with infrared sensors. With this, each classroom is verified three times, if the indicators remain the same, the room is evacuated ”.
