LIS2DH12TR Three-Axis Acceleration Sensor Module

Product Description:
The LIS2DH12TR Three-Axis Acceleration Sensor Module is a high-performance, ultra-low-power accelerometer designed for motion detection, orientation sensing, and industrial applications. Offering a wide dynamic range of ±2g/±4g/±8g/±16g, selectable in real time, this module is an excellent replacement for the popular ADXL345, with enhanced power efficiency and advanced features.

It supports both I²C and SPI digital interfaces, making it easy to integrate into microcontroller and embedded systems. With built-in free-fall detection, motion detection, orientation sensing (4D/6D), FIFO buffer, and a temperature sensor, this accelerometer is ideal for smart devices, wearables, robotics, and industrial monitoring systems.

Key Features:

• Wide Voltage Range: 1.71V – 3.6V, with 1.8V I/O compatibility.

• Ultra-Low Power Consumption: Down to 2μA in low-power mode.
