Physical Sensors
Physical sensors are hardware devices that detect and measure physical properties from the environment, such as temperature, motion, light, or pressure, and convert them into electrical signals for processing by electronic systems. They are fundamental components in embedded systems, IoT devices, robotics, and smart applications, enabling real-world data acquisition. Common types include accelerometers, gyroscopes, proximity sensors, and environmental sensors like humidity or gas detectors.
Developers should learn about physical sensors when building applications that interact with the physical world, such as IoT devices, wearables, automotive systems, or industrial automation, to enable features like motion tracking, environmental monitoring, or user interaction. Understanding sensor integration is crucial for fields like robotics, smart home technology, and healthcare devices, where accurate data collection drives functionality and decision-making.
