This novel CO2 sensor will allow faster and more accurate measurements under conditions such as humidity and high temperature
Carbon dioxide sensors are becoming increasingly important in many applications including monitoring air quality, CO2 sequestration, measuring metabolic activity in animals, and controlling combustion. While commercial sensors for such applications exist, there is nothing currently on the market designed for reliability and effectiveness in high temperature and high humidity environments.
The Ohio State University researchers led by Dr. Prabir Dutta have developed a reliable, high-performance carbon dioxide electrochemical sensor that works across a wide range of temperatures, is insensitive to humidity, and detects CO2 across a wide range of concentrations. An outer layer of barium carbonate is used to physically and chemically protect against humidity and an inner lithium carbonate layer is used for CO2 sensing.
