Fermion: TMF8701 Tof 雷射測距傳感器（10-600mm）

The TMF8701 is a time-of-flight (ToF) distance ranging sensor that 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 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.

A built-in histogram is featured to delivers dynamic cover glass calibration and crosstalk compensation and background light noise is minimized through on-chip sunlight rejection filters.

The TMF8701 outputs data through a I2C fast-mode communications interface and an integrated micro controller, which is featured with all algorithms included on-chip with no need for external optics.
