Detection accuracy: micron-level sensor recognition, accurate distance measurement of obstacles at close range without misjudgment Measuring range: Adjustable in multiple distance settings. It provides dual protection: long-range prediction and short-range deceleration. Layer recognition: distinguish high and low falls to sense, and turn in time to avoid falling when encountering steep cliffs or steps. Durable: Anti-aging photosensitive element ensures consistent sensitivity for many years without gradual decline. Data transmission: Wired signal transmission is stable, ranging data is synchronized with the main control board in real time
