STMicroelectronics VL53L3CX Time-of-Flight Ranging Sensor
STMicroelectronics VL53L3CX Time-of-Flight Ranging Sensor embeds ST's third-generation FlightSense technology. The sensor combines a high-performance proximity and ranging sensor, with multi-target distance measurements and automatic smudge correction. The miniature reflowable package integrates a single-photon avalanche diode (SPAD) array. Physical infrared filters achieve the best ranging performance in various ambient lighting conditions, with a wide range of cover glass windows. The VL53L3CX combines the benefits of a high-performance proximity sensor, with excellent short distance linearity, together with ranging capability up to 3m.
