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.
Jargon buster
Plain-language definitions for the technical terms used above.
- dynamic range
- Dynamic range describes how wide a span of values a sensor can measure, from very low to very high. For a light sensor, a wide dynamic range means it can work in dim indoor settings as well as bright sunlight without changing hardware.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
