Design & development resources

Simulation tool
OPT3101 system estimator tool

The OPT3101 system estimator tool analyzes the performance of the OPT3101, which is a time-of-flight (ToF)-based, long-range proximity and distance sensor analog front end (AFE). The tool determines if the OPT3101 is able to meet design requirements under various conditions.

Software development kit (SDK)
OPT3101 software development kit (SDK)

The OPT3101 software development kit (SDK) provides a C++ library of functions to control and calibrate systems using the OPT3101, which is a time-of-flight (ToF)-based, long-range proximity and distance sensor analog front end (AFE).

IDE, configuration, compiler or debugger
OPT3101 configurator tool

The OPT3101 time-of-flight (ToF) analog front end (AFE) configurator tool is an offline graphical user interface (GUI) for customizing the configuration of the OPT3101, which is a ToF-based, long-range proximity and distance sensor AFE. OPT3101CONFIG-SW provides a high level of (...)

Why choose our time-of-flight (ToF) sensors?


System design flexibility

Detect near and far objects of various shapes, sizes, colors, materials and reflectivity levels in a wide or narrow field of view (FoV).


Precision distance measurements

Accurately detect objects with a 3-mm resolution at a range of 3 cm to 15 m.


Target localization

Determine object distance and direction using up to 3 sensing zones.
