The VL53L0X from STMicroelectronics is a new generation Time-of-Flight (ToF) laser-ranging module housed in the smallest package on the market today, the device provides accurate distance measurement whatever the target reflectance, a major advantage over other conventional technologies. The sensor can measure absolute distances up to 2m in less than 30ms, setting a new benchmark in ranging performance levels, opening the door to various new applications.
The VL53L0X integrates a leading-edge SPAD array (Single Photon Avalanche Diodes) and embeds ST’s second generation FlightSenseTM patented technology. This is a ground-breaking technology allowing absolute distance to be measured independent of target reflectance. Instead of estimating the distance by measuring the amount of light reflected back from the object (which is significantly influenced by colour and surface), the VL53L0X precisely measures the time the light takes to travel to the nearest object and reflect back to the sensor (Time-of-Flight).
The VL53L0X’s 940nm VCSEL emitter (Vertical Cavity Surface-Emitting Laser), is totally invisible to the human eye and when coupled with physical Infrared filters enables longer ranging distance, higher immunity to ambient light and better robustness to cover-glass optical cross-talk.
The VL53L0X can be used in a wide range of applications including but not limited to Robotics (obstacle detection), White goods (hand detection in automatic faucets, soap dispensers etc...), 1D gesture recognition, Laser assisted Auto-Focus in camera and video devices and User detection for Personal Computers/ Laptops/Tablets and IoT (Energy saving) products.
The sensor is easy to integrate as it has a single power supply and requires no additional optics, furthermore the VL53L0 is housed in a LGA12 miniature module measuring just 4.4 x 2.4 x 1.0mm.
Data
The VL53L0X sensor is supported by the P-NUCLEO-53L0A1 evaluation pack which provides an introduction to the ranging and gesture detection features of the VL53L0X sensor, combined with the powerful STM32F401RE microcontroller. The evaluation pack allows designers to develop a basic gesture recognition application using one or two VL53L0X sensors. Two VL53L0X satellite boards can be connected on the X-NUCLEO-53L0A1 expansion board in order to integrate the VL53L0X in a customer’s application.

STMicroelectronics are powering the next generation of Industry 4.0 applications with a new vibration-sensing solution optimized to enable smart maintenance of factory equipment. The IIS3DWB is a system-in-package MEMS sensor featuring a 3-axis digital vibration sensor with low noise over an ultra-wide and flat frequency range. The wide bandwidth, low noise, very stable and repeatable sensitivity, together with the capability of operating over an extended temperature range (up to +105 °C), make the device particularly suitable for vibration monitoring in industrial applications.
