Time-of-flight sensor for mapping, imaging, in distribution
The RFD77402 module is founded on the Simblee platform, which offers an end-to-end development environment for a variety of IoT applications from white goods and consumer and industrial measurement devices to gesture recognition and robotics. The module integrates an embedded light sensor, vertical cavity surface emitting laser (VCSEL) driver, microcontroller and onboard memory to provide highly accurate distance mapping and 3D imaging technology. It uses an eye-safe laser to measure the amount of time it takes to reflect from a given target. The high-repeatability laser features an 850nm wavelength light source and offers an overall sensing distance from 100 mm up to 2 metres. RFD77402 has a 10Hz maximum refresh rate and an I2C interface for device control and data transfer.
Packaging is in a 4.8 × 2.8 × 1.0 mm SMD package, for IoT sensor applications that require accurate distance measurement, user detection, obstacle detection and avoidance, gesture detection and recognition, directional movement and volume or height control. For development in the Simblee ecosystem, the RFD77402 is supported by two development tools: the RFD77306 IoT 3D ToF shield and the RFD77804 Simblee Wireless IoT 3D ToF sensor kit.
