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.
意法半導體推出了VL53L4ED單區間飛行時間(ToF)傳感器，其擴展操作溫度範圍爲-40℃至105℃。VL53L4ED適用於惡劣的環境，可增強在高環境光條件下的鄰近檢測和測距性能，適用於工業工具、智能工廠設備、機器人導航系統、室外照明控制和安防系統等應用。
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.
在擴展意法半導體VL53L4直接飛行時間傳感器系列的同時，VL53L4ED集成了激光發射器和單光子雪崩二極管(SPAD)探測器陣列，是一個方便的一體化模塊，確保即使在極端溫度條件下也可以進行可靠的測量。下一代激光器提供了優異的高環境光環境下的性能和出色的短距離測距精度。此外，傳感器嵌入了處理器，允許省電自主操作和降低對主機系統資源的需求。
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.
意法半導體的新ToF傳感器爲位於整個視場並在完整擴展溫度範圍內的物體提供精確的距離測量，最高可達1150mm。特殊設置可以在強環境光條件下精確測量距離，最高800mm。VL53L4ED傳感器保持距離測量線性度至1mm，並支持高達100Hz的距離測量頻率。
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.
開發人員可以利用X-CUBE-TOF1擴展軟件包，加速使用VL53L4傳感器系列的項目在STM32Cube生態系統中進行。預先使用的軟件包還包括STSW-IMG034驅動程序，可以讓一箇中斷命令將VL53L4ED或VL53L4CD變爲超低功耗接近檢測器，用於用戶檢測、系統激活和非接觸控制。此外，STSW-IMG039軟件包包含用於液位監測的代碼示例。硬件包括NUCLEO-F401RE微控制器板的X-NUCLEO-53L4A3擴展板，可簡化運行代碼示例和構建應用程序，以及用於原型製作的SATEL-VL53L4ED斷開電路板。
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傳感器都支持與針腳兼容，並提供4.4mm x 2.4mm x 1mm高的LGA封裝。新的VL53L4ED已經在生產中了，價格爲每4500件2.3美元。
