Digital Laser Proximity Sensor

SKU: SEN0531

This digital laser proximity sensor (advanced SEN0381) offers longer sensing distance and a real-time status indicator. Press the on-board button for 3s to adjust detection distance (1-400cm) and auto-save obstacle distance. With digital output compatible with Arduino, it’s used in smart home, security, intelligent detection/control, robot obstacle avoidance. Based on laser diffuse reflection: triggers signal when objects enter range, stops when leave for intelligent control.
