A Smart Interface for Gas Pollution Detection

A smart interface prototype system was developed (Fig. 1) to detect presence as well as the strength of CO2, CO, NH3, NxOy, methane, butane, alcohol, LPG gases including fumes/smell in air or in a chamber. Output would be displayed on LCD bar for indication of air quality or gas pollution level in the air for low, medium, high, very high and extremely high with a numeric display.
