Pressure sensing is the process of detecting and measuring the force exerted by a fluid (liquid or gas) on a surface. This is typically done using devices called pressure sensors or pressure transducers, which convert the physical pressure into an electrical signal. These sensors are widely used in various applications, including automotive systems, weather monitoring, and industrial processes. The data collected by pressure sensors can help monitor conditions, ensure safety, and improve efficiency. For example, in automobiles, pressure sensors can monitor tire pressure, while in medical devices, they can measure blood pressure. This information is crucial for making informed decisions and maintaining optimal performance.
