This sensor is perfect for when you need to detect the presence of many different gases in non-specific amounts, for example, natural gas or propane. It also senses alcohol, so it could be used as a breathalyzer as well. Measurements can be taken instantaneously due to the sensor's fast response time and high sensitivity, which can be adjusted by using the built-in potentiometer.
