RF Digital RFD77402 Simblee time-of-flight (ToF) sensor module

The RFD77402 Simblee Internet of Things (IoT) 3D time-of-flight (ToF) sensor module, from RF Digital, integrates an embedded light sensor, vertical cavity surface emitting laser (VCSEL) driver, microcontroller and onboard memory to provide distance mapping and 3D imaging technology. It is founded on the Simblee platform, which offers an end-to-end development environment for a variety of IoT applications from whitegoods and consumer and industrial measurement devices to gesture recognition and robotics.

The module uses the eye-safe laser to measure the amount of time it takes to bounce off a given target. The high-repeatability laser features an 850 nm wavelength light source and offers an overall sensing distance from 100 mm up to 2 m.

The module is available in an ultrasmall 4.8 x 2.8 x 1 mm SMD package and is suitable for a broad array of IoT sensor applications that require correct distance measurement, user detection, obstacle detection and avoidance, gesture detection and recognition, directional movement and volume or height control. It offers a 10 Hz maximum refresh rate and an I²C interface for device control and data transfer.
