Plug and Play Colorimetric Carbon Dioxide Sensor
Abstract
Carbon dioxide measurement is an important endeavor in many industries such as food packaging, grain storage and health industry. This work presents a reversible, plug and play and low-cost colorimetric CO2 sensor calibrated in a proper concentration ranging from 1% to 3% of CO2. The sensor showed potential for improvement to increase resolution, for measuring lower CO2 concentrations and for more accurate readings.
