New Time-of-Flight Ranging Sensor from STMicroelectronics Boosts Range and Speed, in Industry’s Smallest Footprint

STMicroelectronics has further enhanced its leadership in Time-of-Flight (ToF) ranging sensors with the second generation of its FlightSense™ technology, now available in the new VL53L0X laser-ranging sensor. The VL53L0X extends the ToF measurement range to two meters, and is accurate to within ±3%. It is also faster, measuring the distance in under 30ms, and highly energy-efficient, consuming only 20mW in active ranging mode and drawing 5µA in standby. At 2.4mm x 4.4mm x 1mm, it is also the smallest such device in the market. Unlike conventional infrared proximity sensors, the VL53L0X gives accurate distance measurement in millimeters, and is unaffected by the color or reflectivity of the sensed target. Its fast-acting FlightSense technology, well known from the laser-assisted camera auto-focus featured in several smartphones from top brands, can also distinguish movement towards or away from the sensor or from side to side. Distance is calculated internally and communicated over I2C thereby minimizing demands on the system host controller.”
