Resistive sensors are devices that measure physical quantities by detecting changes in electrical resistance. When an external factor, such as temperature or pressure, affects the sensor, its resistance changes, which can be measured and converted into a readable signal. Common types of resistive sensors include thermistors for temperature measurement and strain gauges for detecting deformation. These sensors are widely used in various applications, including industrial automation, automotive systems, and consumer electronics. Their simplicity and reliability make them popular choices for monitoring and controlling processes in real-time, ensuring accurate data collection and system performance.
