STMicroelectronics Reveals New Single-zone Direct-ToF Sensor With Extended Operating Temperature for Industrial Applications
STMicroelectronics has introduced the VL53L4ED single-zone Time-of-Flight (ToF) sensor, which has an extended operating temperature range from -40°C to 105°C. Ready for harsh environments, the VL53L4ED enhances proximity detection and ranging under high ambient light conditions in applications such as industrial tools, smart-factory equipment, robot guidance systems, outdoor lighting controls, and security systems.
意法半导体推出了VL53L4ED单区间飞行时间(ToF)传感器，其扩展操作温度范围为-40℃至105℃。VL53L4ED适用于恶劣的环境，可增强在高环境光条件下的邻近检测和测距性能，适用于工业工具、智能工厂设备、机器人导航系统、室外照明控制和安防系统等应用。
Expanding ST's VL53L4 family of direct-ToF sensors, the VL53L4ED integrates a laser emitter and a single-photon avalanche-diode (SPAD) detector array in a convenient all-in-one module which ensures reliable measurement even in extreme temperature conditions. The next-generation laser provides enhanced performance in high ambient light environments and excellent short-distance ranging accuracy. In addition, the sensors embed a processor that allows power-saving autonomous operation and lowers demand for host-system resources.
在扩展意法半导体VL53L4直接飞行时间传感器系列的同时，VL53L4ED集成了激光发射器和单光子雪崩二极管(SPAD)探测器阵列，是一个方便的一体化模块，确保即使在极端温度条件下也可以进行可靠的测量。下一代激光器提供了优异的高环境光环境下的性能和出色的短距离测距精度。此外，传感器嵌入了处理器，允许省电自主操作和降低对主机系统资源的需求。
ST's new ToF sensor provides high-accuracy distance measurement to objects up to 1150mm away, throughout the entire field of view and over the full extended temperature range. Special settings allow accurate distance measurement up to 800mm under strong ambient light conditions. The VL53L4ED sensor maintains distance-measurement linearity down to 1mm and supports ranging frequency up to 100Hz.
意法半导体的新ToF传感器为位于整个视场并在完整扩展温度范围内的物体提供精确的距离测量，最高可达1150mm。特殊设置可以在强环境光条件下精确测量距离，最高800mm。VL53L4ED传感器保持距离测量线性度至1mm，并支持高达100Hz的距离测量频率。
Developers can take advantage of the X-CUBE-TOF1 expansion software package for the STM32Cube ecosystem to accelerate projects using the VL53L4 sensor family. Ready-to-use software includes as well the STSW-IMG034 driver that lets an interrupt command turn the VL53L4ED or VL53L4CD into an ultra-low-power proximity detector for user detection, system activation, and touchless control. In addition, the STSW-IMG039 software pack contains code examples for liquid-level monitoring. Hardware includes the X-NUCLEO-53L4A3 expansion board for the NUCLEO-F401RE microcontroller board, which eases running code examples and building applications, as well as the SATEL-VL53L4ED breakout board for prototyping.
开发人员可以利用X-CUBE-TOF1扩展软件包，加速使用VL53L4传感器系列的项目在STM32Cube生态系统中进行。预先使用的软件包还包括STSW-IMG034驱动程序，可以让一个中断命令将VL53L4ED或VL53L4CD变为超低功耗接近检测器，用于用户检测、系统激活和非接触控制。此外，STSW-IMG039软件包包含用于液位监测的代码示例。硬件包括NUCLEO-F401RE微控制器板的X-NUCLEO-53L4A3扩展板，可简化运行代码示例和构建应用程序，以及用于原型制作的SATEL-VL53L4ED断开电路板。
All the VL53L4 sensors are pin-compatible and offered in a 4.4mm x 2.4mm x 1mm-high LGA package. The new VL53L4ED is in production now, priced from $2.3 for 4500 pieces.
所有VL53L4传感器都支持与针脚兼容，并提供4.4mm x 2.4mm x 1mm高的LGA封装。新的VL53L4ED已经在生产中了，价格为每4500件2.3美元。
