SEN0429, Fermion: TMF8701 ToF Distance Ranging Sensor (10-600mm) (Breakout)

The SEN0429 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 colour, 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.

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

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