Description
Unit ToF is a laser-ranging Unit. It integrates the VL53L0X laser-ranging module, which calculates the distance between the emission point and the object detected by measuring the round-trip time of the laser signal. Unlike traditional ranging, it can provide accurate distance measurement data regardless of the reflectivity of the target. Emitting laser light with a wavelength of 940nm, it can measure an absolute distance of up to 2m in less than 30ms.

Measurement Distance
Under normal conditions, the maximum test distance is 120cm; to reach 200cm, you need to set Long Range mode and ensure a dark environment without infrared interference.
