VL53L7CHV9GC/1

The VL53L7CH is the perfect Time-of-Flight sensor enabling AI applications, with ultrawide 90° diagonal FoV and low power consumption. The compact and normalized histogram (CNH) innovative data output is specially designed for artificial intelligence (AI) applications requiring multizone raw data from a high performance multizone ToF sensor.

The IR signal measured in each zone is sent as raw data to the host through each bin of the histogram. Highly configurable, the user can program the resolution of the VL53L7CH up to 64 zones (8x8 zones), modify the histogram resolution up to 128 bins, and define the bin width. All this CNH data is transmitted to the host through I²C, up to 30 Hz, in addition to the standard processed data of the ToF sensor (ranging distance, signal level, reflectance etc.).

The CNH data transform ST Time-of-Flight ranging sensor into a versatile optical sensor, which can enable endless AI-based applications. This CNH raw data sent to the host, on top of the standard ranging data, opens the door to many new applications beyond simple distance measurements. From solid material (carpet, wood, glass, mirror...) to gas or liquid (water, oil, chemical...), it becomes possible to detect the location and the size of a cup in a coffee machine or beverage dispenser, to sense the floor material for robotics, and develop advanced shape, motion, or hand posture recognition.

The VL53L7CH Time-of-Flight sensor offers an ultrawide 90° diagonal FoV, shaped as a square 60° x 60° FoV, thanks to the innovative metalens surface ODIF lenses. The integrated VCSEL emits fully invisible 940 nm IR light, which is Class 1 certified and safe for the eyes.
