This function is performed by a gyro sensor
A gyroscope is a module that can be used to measure rotational movement. Specifically, this means that a rotation sensor provides the following data:
- Degree of rotation or number of rotations
- Rotational speed
A gyroscope is located in the respective object and answers the question: How often and at what speed does the object rotate around its own axis? It also measures partial rotations and thus determines the angle of inclination.
These gyro sensors are used in a wide range of applications. Typical examples are:
Gyroscope sensor in cars:
The sensors supplement GPS technology for navigation. With the help of a gyro-based system and the distance travelled, the current position of the vehicle can be calculated. This proves to be important when no GPS signals are available.
Gyroscope in mobile phones:
As in cars, the sensor supports navigation. It also detects the tilt of the smartphone for many other purposes, such as controlling games.
Gyroscopes in robotics:
In this innovative field, gyroscope sensors are also an important component for navigation and thus for controlling devices.
In addition, manufacturers equip aircraft, rockets, drones and other flying objects as well as vehicles with sensors for measuring rotational movements.
How does a gyroscope work?
All gyrometers measure the rotational movements of rotating bodies. However, the exact technology used for this measurement varies significantly depending on the design. For a long time, simple mechanical designs dominated the market, but today optical systems such as laser gyroscopes and microelectromechanical systems (MEMS) are particularly widespread.
Here in our shop, you can purchase inexpensive and compact MEMS designs. These small components can be easily integrated into integrated circuits – a big advantage! The low acquisition costs are also beneficial.
Buying the right gyroscope: tips
If you need a reliable rotation rate sensor for your project, EXP Tech has the tailor-made solution for you! When making your selection, please note that the range of gyro sensors is huge.
It is important to consider the accuracy with which the sensor should detect rotational movements. Another criterion is whether a gyroscope sensor is sufficient or whether you require additional sensors. Many models, for example, have an additional magnetometer and an acceleration sensor.
