Overview
The LIS3L02AQ5TR is a low-power, 3-axis linear capacitive accelerometer produced by STMicroelectronics. This device integrates a sensing element and an IC interface, enabling it to convert detected accelerations into analog signals. The accelerometer is designed using a proprietary process to create surface micro-machined structures, allowing for high accuracy and reliability. It operates within a temperature range of -40°C to +85°C and is packaged in a 44-pin QFN (Quad Flat No-Lead) package.
