Sensor technology refers to devices that detect and respond to physical stimuli, such as light, heat, motion, or pressure. These sensors convert the detected information into signals that can be measured and analyzed. Common examples include temperature sensors, motion detectors, and pressure sensors, which are widely used in various applications, from home automation to industrial processes. The data collected by sensors can be used to monitor conditions, automate systems, and improve efficiency. For instance, in smart homes, temperature sensors help regulate heating and cooling, while motion detectors enhance security by alerting homeowners to movement.
