Fermion: TMF8801 ToF Distance Ranging Sensor (20-2500mm)

The TMF8801 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 TMF8801 offers a high dynamic range and detection sensing measurements from 2-250cm distances. 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 TMF8801 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.
