Acceleration sensor

In mobile and wearable devices, acceleration sensors are becoming standard components. For example, in smartphones and tablets, three-axis accelerometers enable screen rotation; in wristbands and smartwatches, three-axis accelerometers enable functions such as pedometer and sleep monitoring; in TWS earbuds, three-axis accelerometers serve as a human-computer interaction interface, recognizing operations such as single-click and double-click.

Product Description

Product Features:

　　In mobile and wearable devices, accelerometers are becoming standard components. For example, in smartphones and tablets, three-axis accelerometers enable screen rotation; in wristbands and smartwatches, three-axis accelerometers enable functions such as pedometer and sleep monitoring; in TWS earphones, three-axis accelerometers serve as a human-computer interaction interface, recognizing single clicks, double clicks, and other operations.

　　Minsic has the full-process design capability of accelerometers, including MEMS design, ASIC design, packaging, and testing. The products have rich functions, multiple interrupt outputs, and a built-in 32-depth FIFO, which can effectively reduce the system power consumption of the whole machine, especially suitable for applications such as wristbands and watches with strict power consumption requirements.
