STMicroelectronics VL53L0X 飞行时间测距传感器

STMicroelectronics VL53L0X 飞行时间测距传感器是新一代激光测距模块，采用市场上尺寸最小的一种封装。VL53LOX 是完全集成的传感器，配有嵌入式红外、人眼安全激光，先进的滤波器和超高速光子探测阵列。VL53L0X增强了ST FlightSense™系列，测量距离更长，速度和精度更高，从而开启了新应用之门。

The sensor can directly determine the distance to a target object, up to 2m, even in challenging operating conditions and independent of target reflectivity. The VL53L0X is ideally suited for wireless and IoT and is designed with an ultra-low-power system architecture.
