What is the main function of sensors in engineering technology applications?

The main function of sensors in engineering technology applications is to detect and respond to physical stimuli. Sensors are designed to measure various forms of physical phenomena—such as temperature, pressure, light, motion, and sound—and convert these measurements into signals that can be interpreted by electronic systems or computers. This ability to sense and respond is crucial in automation, robotics, monitoring systems, and various engineering applications, allowing for real-time data collection and analysis.

This capacity enhances the functionality and efficiency of systems, enabling applications like automatic temperature control in HVAC systems, smart home devices, and safety monitoring in industrial settings. The integration of sensors leads to improved decision-making and operational efficiencies, which is a fundamental aspect of modern engineering technology.
