How Do Pressure Sensors Work?
Pressure sensors operate by converting pressure measurements into an electrical signal that can be easily interpreted and analyzed. They typically consist of a sensing element, such as a piezoelectric crystal, which deforms under pressure. This deformation generates an electrical charge, which is then processed to provide a pressure reading.
