Time-of-Flight Sensor
A Time-of-Flight (ToF) sensor is an electronic device that measures the distance to an object by calculating the time it takes for light (typically infrared) to travel from the sensor to the object and back. It uses a light source, such as a laser or LED, and a photodetector to capture the reflected signal, enabling precise depth sensing and 3D imaging. This technology is widely used in applications like gesture recognition, robotics, augmented reality, and autonomous systems for real-time spatial awareness.
Developers should learn and use Time-of-Flight sensors when building projects that require accurate, real-time distance measurement or 3D mapping, such as in robotics for obstacle avoidance, smartphones for facial recognition and autofocus, or industrial automation for object detection. It is particularly valuable in scenarios where traditional sensors like ultrasonic or infrared proximity sensors lack precision or speed, offering sub-millimeter accuracy and fast response times for dynamic environments.
