Electronic sensors are devices that detect and respond to physical stimuli, such as light, temperature, motion, or pressure. They convert these stimuli into electrical signals, which can be measured and analyzed. Common examples include temperature sensors, motion detectors, and light sensors, each serving various applications in industries like automotive, healthcare, and environmental monitoring. These sensors play a crucial role in modern technology, enabling automation and improving efficiency. For instance, smart home systems use electronic sensors to control lighting and heating based on occupancy, while industrial sensors monitor machinery performance to prevent failures. Their versatility makes them essential in everyday life.
