STMicroelectronics announces its first multi-zone FlightSense dToF sensor for general-purpose applications. The VL53L5CX sensor provides up to 64 sensing zones with multi-target detection, distance measurement up to four meters in each zone, and a wide square-edged field of view with 63° diagonal.

 The sensor is suited to gesture recognition, complex scene analysis including 3D room mapping for robotics, storage-tank level monitoring to assist in inventory management, liquid-level control, and waste-bin-level monitoring to enable smart refuse collection for enhanced efficiency.

Featuring ST’s histogram processing, which greatly reduces the impact of cover-glass crosstalk, the sensor can be integrated and hidden behind various types of front panels. The new motion-indicator feature allows the sensor to detect if the target has moved or not.

The number of sensing arrays is programmable and the sensor can provide up to 60 fps in 16-zone (4×4) mode for fast-ranging mode. With simple software configuration to reach high resolution of 8×8 zones, the VL53L5CX can also assist keystone correction for video projectors and provide an accurate mini depth-map for AR/VR applications.

The VL53L5CX contains a low-power microcontroller and is capable of autonomous operation for power-saving applications. It comes in a fully integrated 6.4mm x 3.0mm x 1.5mm module that contains an infrared VCSEL and a receiver with embedded SPADs and histogram based ToF processing engine.

All parts are in production now, priced from $3.90.
