Gyroscopes are motion sensors that measure the angular rate of rotation around a specific axis. They allow us to measure the orientation of an object or the direction of acceleration. The L3GD20TR is a three-axis gyroscope made by STMicroelectronics that is designed to help detect the angle of rotation in all axes of motion.

Application field

Gyroscopes, including the L3GD20TR, are used in many applications including aircraft navigation, robotics, gaming, and smartphones. In avionics, the gyroscope is used to detect the orientation of the aircraft and to control its attitude. This is necessary for stable flight. It is also used in the flight simulation machines for training pilots. In robotics, the gyroscope helps to keep the robot balanced and control the robot’s orientation, allowing the robot to move accurately and safely. Gyroscopes are used in gaming devices such as wands and virtual reality (VR) headsets to detect the position and orientation of the device. In smartphones, gyroscopes are used to detect the device’s orientation, allowing the device to change its view based on the orientation of the phone.

Working principle

The L3GD20TR gyroscope works by measuring the Coriolis force. Coriolis force is a type of acceleration that is produced by a rotating body. It causes the object to move in a direction perpendicular to the direction of motion. The force is proportional to the angular velocity of the body. The gyroscope works by using a vibrating structure inside a sealed housing. The structure is made up of a mass and two or more proof masses connected to it. When the device is placed in a moving environment, the Coriolis force will cause the vibrating structure to oscillate. This oscillation can be measured by an accelerometer and is a measure of the angular rate of motion. The L3GD20TR also has a temperature sensor built onto the package to ensure accurate readings when the environment changes.

The L3GD20TR comes with a three-axis digital output and has a wide range of applications. It offers several features such as high sensitivity, low power consumption, and high interference immunity. It is also designed to have high shock and vibration resistance. These features make the L3GD20TR an ideal choice for a wide range of applications.
