Can a CO2 monitor warn you when indoor air is bad?

CO2 transmitter for LEED

While most of us seal our homes and offices to save energy, few of us consider the unintended consequences. You know what you’re keeping out, but have you ever thought about what you’re keeping in?

The eSense Fresh Air Indicator (FAI) warns you when indoor air is likely to contain high levels of dust, chemicals and micro-organisms. It can be used in offices, classrooms or anywhere air quality is important. An audible warning and flashing light indicate too much carbon dioxide, which means additional fresh air ventilation is required.

Measuring indoor carbon dioxide levels is an accepted world-wide standard indoor air quality. Proper ventilation has also been shown to increase productivity and the ability to learn according to several documented studies.

“Think of carbon dioxide as the ‘canary in the mineshaft’”, says Ray Hicks, President of “As the number of people in an enclosed space increase, CO2 levels rise. When CO2 is too high, so are airborne levels of dust, mold, bacteria, viruses and volatile organic compounds from carpets, perfumes and other sources.”

Originally developed at the request of environmental engineers, the FAI is designed to meet the LEED specifications for CO2 monitoring for indoor air quality. LEED (Leadership in Energy and Environmental Design) is the nationally accepted benchmark for the design, construction and operation of energy efficient and healthy “green” buildings.

The eSense FAI can be plugged into the wall, or it can be connected to a demand controlled ventilation system.
