Motion detection sensors are designed to identify physical movement in an environment and trigger responses in electronic systems. These sensors are widely used in automation, security systems, robotics, and IoT applications where detecting presence or movement is essential.
Common types include PIR (Passive Infrared) sensors for human motion detection, vibration sensors for detecting physical disturbances, and tilt sensors for orientation-based movement. These sensors typically provide digital or analog outputs and are easy to integrate with microcontrollers like Arduino, Raspberry Pi, and other embedded platforms.
