Working principle of gravity sensor:

The gravity sensor works based on the principle of piezoelectric effect. Due to the acceleration of a certain medium, the deformation is measured and converted into a voltage output using related circuits.

Application of gravity sensor:

By measuring the acceleration caused by gravity, the tilt angle of the device relative to the horizontal plane can be calculated. For example, a mobile phone with a gravity sensor can sense the screen status and Automatically adjust the screen to keep it level.

By analyzing dynamic acceleration, you can analyze the way the device moves. For example: it can sense whether a person is sitting quietly or exercising, and select appropriate music to play.

The acceleration sensor can help the device understand the environment it is currently in, such as: electronic product fall alarm.​ ​
