DFRobot presents the three-axis accelerometer Arduino with extremely low power consumption. This product is based on the MEMS LIS2DH chip solution and features high performance in very low power mode. The sensor is equipped with a Gravity I2C interface for easy installation in your projects. The built-in LDO power management chip offers a wide input voltage range, from 3.3 to 5V. The integrated I2C level conversion makes the sensor compatible with both 3.3V and 5V devices. Compared to the traditional ADXL345, the LIS2DH accelerometer offers advantages such as greater stability and more efficient power consumption. The low-power mode requires only 2μA, while the normal mode requires 11μA. At maximum performance, the module supports an output frequency of 5.3KHz. Sensitivity levels are adjustable to ±2g, ±4g, ±8g, or ±16g, and the module supports 16-bit data outputs. There are 2 independent programmable interrupt generators for free fall detection and motion detection.
