FAQ

A capacitive accelerometer sensor measures acceleration by detecting changes in capacitance between microstructures inside the sensor. When the device moves, the distance between these structures changes, causing the capacitance value to change and generating a corresponding electrical signal. Such sensors feature high sensitivity, low power consumption, and long-term stability, making them ideal for precise motion detection in industrial and scientific applications.

Miniature capacitive accelerometer sensor (three-axis) are widely used in structural health monitoring, vehicle attitude detection, industrial equipment vibration analysis, and mobile device attitude sensing. Their compact design is suitable for space-constrained embedded systems, enabling real-time capture of acceleration changes along the X, Y, and Z axes, thereby enhancing the system's dynamic response capability and measurement accuracy.

The accelerometer sensor features a high-stability capacitive MEMS structure internally, offering excellent temperature drift compensation and anti-interference performance.
