Humidity-Interference Free, High-Temperature CO2 Sensor
Summary
Carbon dioxide sensors are becoming increasingly important in many applications including monitoring air quality and emissions, measuring metabolic activity in animals, and controlling combustion. While commercial sensors for air quality monitoring exist, there is nothing currently on the market designed for reliability and effectiveness in high temperature and high humidity environments. Researchers at The Ohio State University have developed a reliable, high-performance carbon dioxide electrochemical sensor that works across a wide range of temperatures, insensitive to humidity, detects CO2 from ppm to percent levels. These sensors can be manufactured by thin and thick film processing techniques, therefore can be miniaturized with milliwatt power requirements for operation.
