Time-of-Flight Sensor
A Time-of-Flight (ToF) sensor is a device that measures the time it takes for light or other signals to travel to an object and back, enabling precise distance measurement and 3D imaging. It typically uses infrared light pulses or laser beams to calculate depth information, making it essential for applications like gesture recognition, object detection, and spatial mapping. These sensors are widely used in robotics, augmented reality, and autonomous systems for real-time environmental perception.
Developers should learn about Time-of-Flight sensors when working on projects requiring accurate depth sensing, such as robotics navigation, AR/VR applications, or smart home devices, as they provide fast and reliable distance data. They are particularly useful in scenarios where traditional cameras or ultrasonic sensors fall short, such as low-light conditions or complex environments, due to their high precision and immunity to ambient light interference.
