STM Time-of-Flight Ranging Sensor icroelectronics VL53L3CX
STM Time-of-Flight Ranging Sensor icroelectronics VL53L3CX
The VL53L3CX time-of-flight ranging sensor is embedded with ST's third-generation FlightSense technology. The sensor combines high-performance proximity and ranging sensors, multi-target distance measurement and automatic smudge correction. The miniature reflowable package integrates a single photon avalanche diode (SPAD) array. The physical infrared filter can achieve the best ranging performance under various environmental lighting conditions, and has a variety of cover glass windows. VL53L3CX combines the advantages of a high-performance proximity sensor, excellent short-distance linearity, and a distance measurement capability of up to 300CM.
