A basic piezoelectric gas sensor operates on the principle of the piezoelectric effect, which is the generation of an electric charge in certain materials in response to applied mechanical stress. In the context of gas sensing, this effect is used to detect the presence of specific gases by measuring the mechanical deformation caused by gas molecules interacting with the sensor's surface.
Here's how a basic piezoelectric gas sensor operates:
Sensor Construction: The sensor is typically made up of a piezoelectric material, such as quartz
