Time-of-flight sensor
The time-of-flight sensor (also referred to as a ToF sensor) emits an infrared laser and uses the reflected
infrared energy to measure the distance and depth of objects in front of it. The data collected by the sensor
can be used to detect human presence or recognize gestures.
Note: The infrared laser emitted by the ToF sensor is invisible to the human eye.
