Product Introduction

Overview

The LIS3L02AQ3TR is a low-power, 3-axis linear capacitive accelerometer produced by STMicroelectronics. This device is part of a family of inertial sensors designed for various applications requiring precise acceleration measurements. The LIS3L02AQ3TR includes a sensing element and an IC interface, which converts the mechanical acceleration into an analog signal. Although this product is now obsolete, it was widely used in mobile terminals, gaming and virtual reality input devices, free-fall detection, antitheft systems, and inertial navigation.
