Mechanical sensors are devices that detect physical changes in their environment and convert these changes into measurable signals. They can sense various parameters such as pressure, force, displacement, and acceleration. Common examples include pressure sensors, strain gauges, and accelerometers, which are widely used in industries like automotive, aerospace, and manufacturing. These sensors work by responding to mechanical stimuli, such as movement or force, and translating that information into electrical signals. This allows for real-time monitoring and control of systems, enhancing safety and efficiency in applications ranging from robotics to smart home technology.
