A mechanical sensor is a device that detects physical changes in its environment and converts them into measurable signals. These sensors can respond to various stimuli, such as pressure, force, or displacement, and are commonly used in applications like automotive systems, industrial machinery, and consumer electronics. Mechanical sensors often utilize components like springs, levers, or diaphragms to sense changes. For example, a pressure sensor may use a diaphragm that bends under pressure, triggering an electrical signal. This technology is essential for monitoring and controlling systems, ensuring safety and efficiency in various fields.
