CO2 monitor lending library

WUU is excited to contribute towards a lending library of carbon dioxide monitors to assess air quality on campus.

With the elimination of the campus mask mandate last March, there are important concerns about air quality and ventilation in classrooms and other spaces at UW-Madison. Air quality is an important factor in the spread of airborne diseases such as COVID-19. Campus administration has not been forthcoming about efforts to assess or improve air quality. The Facilities HVAC FAQ is particularly disappointing as it discourages any efforts to assess air quality, improve air ventilation, or filter air in university spaces.

A group of campus workers and community members has designed a low-cost CO2 monitor and are seeking to lend them out to the campus community, to assess air ventilation in classrooms and other campus spaces. They have 18 CO2 monitors available for use; WUU has contributed funds for 10 of them.

Hand-made CO2 monitor built with a $40 CO2 sensor, a $10 microcontroller, a $5 LCD display, and a 50 cent plastic box.
