Barometer measures air pressure. This air pressure is used to measure the height of the drone. As we move to higher altitude, the air pressure decreases.
The sensor identifies air pressure liftingu00a0 at a low altitude, near sea level.
Drones utilize air pressure sensors to stabilize altitude, allowing hover capabilities needed for videography or photography.
Combined with the accelerometer and gyroscope, barometric pressure sensors enable drones to fly with precision.
