What Is a Time of Flight Sensor (ToF)?

The time of flight sensor (ToF) has a peculiar name. It doesn’t necessarily mean it will calculate the time a flying object is in the air, nor does it measure the precise time an object takes off from the ground. Before understanding what a ToF sensor does, it’s essential to understand what ToF actually is. ToF measures the time it takes for a physical object to travel a given distance through a medium. Typically, this measurement can determine velocity and path length, but it can also be used to learn about an object’s dimensions.
