A TOF (Time-of-Flight) sensor is a device that measures distance by calculating the time it takes for a light signal (usually a laser or LED pulse) to travel to an object and back to the sensor. This technology enables accurate distance measurement, 3D mapping, gesture recognition, and object detection in applications like robotics, smartphones, and industrial automation.

- VL6180
Time-of-Flight (ToF) proximity sensor
The VL6180 is the latest product based on ST’s patented FlightSense™ 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 color and surface), the VL6180 precisely measures the time the light takes to travel to the nearest object and reflect back to the sensor (Time-of-Flight).
