Working Principle of the LIS3L02AQ3TR

The LIS3L02AQ3TR is based on a capacitive sensing principle. It consists of a mass formed by a substrate, and an arrangement of silicon, suspended between two electrodes. This arrangement is formed of a fixed plate and a stator that moves over it, causing a change in the capacitance between them. This changing capacitance is process by the device, to detect position, acceleration, and orientation.

The LIS3L02AQ3TR includes a g-force-based detection element, such as a two-axis acceleration sensor, with the ability to detect position, resonance frequency and peak frequency, thus providing an enhanced accuracy when measuring the acceleration and detecting angular velocity. This device also includes a look-up table that can store up to eleven acceleration thresholds.

The LIS3L02AQ3TR also includes embedded self-calibrating algorithms that allow for an optimized output. In order to achieve the highest accuracy, the accelerometer has a low-noise architecture, which minimizes the noise and ensures that the accelerometer\'s output is as precise as possible.

The LIS3L02AQ3TR features a programmable interrupt feature that can be set to detect changes in the acceleration, position, and/or orientation of the device. Additionally, the LIS3L02AQ3TR includes a sample-and-hold feature designed to reduce power consumption. This accelerometer also provides a low-power sleep mode.
