Inertial Measurement Units (IMU)

The IMU is a key sensor in drones that measures the drone's acceleration and orientation. It includes:

Accelerometers: Measure changes in velocity (acceleration) and detect tilt angles.
Gyroscopes: Measure rotational speed and help maintain stability during flight.

Role of the IMU:

The IMU helps the drone stay level and balanced by constantly feeding data to the flight controller, which adjusts motor speeds to maintain the desired orientation and stability.

Example:

When you pitch the drone forward to fly, the IMU detects the change in angle and ensures that the drone maintains stability while moving.
