What sensors are used in drones?

Modern drones may use several types of sensing technologies, including:

• Vision sensors for object detection and depth estimation
• Infrared sensors for hovering and ground detection
• LiDAR for precise depth mapping
• Radar for obstacle detection in poor visibility
• GPS and positioning systems for navigation and stability

The combination of sensors varies depending on the drone model and intended use.
