📱✨ List of Sensors in Today’s Mobile Phones

🔹 1. Accelerometer

• Detects: Phone movement, tilt, and orientation

• Use: Auto-rotate screen, step counting, gaming controls

🔹 2. Gyroscope

• Detects: Rotation and spin direction

• Use: Augmented reality (AR), gaming (like racing), 360° camera apps

🔹 3. Magnetometer

• Detects: Magnetic fields (like a compass)

• Use: Digital compass, metal detection apps, GPS enhancement

🔹 4. Proximity Sensor

• Detects: How close your face is to the screen

• Use: Turns screen off when you're on a call to save battery and avoid touches

🔹 5. Ambient Light Sensor

• Detects: Light levels around the phone

• Use: Auto-adjust screen brightness to match surroundings

🔹 6. Barometer

• Detects: Air pressure

• Use: More accurate GPS (elevation), weather apps, altitude tracking

🔹 7. Fingerprint Sensor

• Detects: Your fingerprint pattern

• Use: Security unlock, app authentication (banking, etc.)

🔹 8. Face Recognition Sensor (Infrared / 3D Time-of-Flight)

• Detects: Depth and shape of your face

• Use: Face unlock, secure access

🔹 9. GPS Sensor

• Detects: Your location using satellites

• Use: Maps, ride apps, location sharing, games (like Pokémon GO)

🔹 10. Microphone

• Detects: Sound

• Use: Voice calls, voice assistant, video/audio recording.

🔹 11. Camera Sensors (RGB, Depth, Ultrawide, Macro, etc.)

• Detects: Light, distance, detail

• Use: Photos, video, AR, face filters

🔹 12. Infrared (IR) Sensor (on some phones)

• Detects: Heat signatures or used as remote controller

• Use: Controlling TVs, ACs, or night vision

🔹 13. Hall Sensor

• Detects: Magnetic field changes (like when using flip covers)

• Use: Auto wake/sleep screen when using magnetic phone covers

🔹 14. Thermometer / Temperature Sensor (Internal/External)

• Detects: Temperature of device or environment (some models)

• Use: System health, overheating alerts, some smart health apps

🔹 15. LiDAR Scanner (on advanced phones like iPhone Pro)

• Detects: Depth with laser pulses

• Use: Professional AR, 3D scanning, better low-light focus in camera
