DFRobot Fermion TMF8701 ToF Distance Ranging Sensor uses the time difference between light pulses to measure distance. It provides single-zone detection of an object irrespective of the color, reflectivity, and texture of the object. The TMF8701 offers a high dynamic range and operates in either a proximity mode (1 –10cm) or a ranging mode (10–60cm) for detection sensing. And the device can make highly accurate distance measurements within ±5% and is capable of operation in dark environments and in the presence of sunlight.
