This digital IR Proximity Sensor features an on-board button, indicator, adjustable 0-200cm detection distance, and real-time feedback. Press the button (indicator flashes) to adjust; it auto-saves the obstacle distance. Equipped with a 3PIN data cable for Arduino, it’s used in smart home, security, robot obstacle detection, etc. Based on IR diffuse reflection, it outputs signals when objects enter/leave the range for intelligent control.
