Overview
The LIS302DL is an ultra-compact, low-power, three-axis linear accelerometer produced by STMicroelectronics. It integrates a sensing element and an IC interface, enabling the measurement of acceleration in three axes and providing the data through I2C/SPI serial interfaces. The sensing element is manufactured using a dedicated process to produce inertial sensors and actuators in silicon, while the IC interface is manufactured using a CMOS process to ensure high integration and precision. The device is designed for a wide range of applications requiring precise acceleration measurements and low power consumption.
