⚙️ How the GY-511 LSM303DLHC Sensor Works

The GY-511 LSM303DLHC 3-axis E-Compass Sensor integrates two sensing elements:

1. 3-Axis Accelerometer
   Measures acceleration forces along X, Y, and Z axes. It helps detect:

   • Device orientation

   • Tilt angle

   • Motion and vibration

2. 3-Axis Magnetometer
   Measures Earth’s magnetic field in three dimensions, allowing:

   • Compass heading detection

   • Directional orientation

   • Magnetic field strength measurement

By combining data from both sensors, the module provides tilt-compensated compass output, ensuring accurate heading information even when the device is not perfectly level.
