| Gravity I2C Triple Axis Accelerometer LIS2DH SKU:SEN0224 Introduction DFRobot presents the ultra low-power Arduino triple axis accelerometer! This device is based around a MEMS LIS2DH chip solution and has high-performance ultra-low power mode. The module is fitted with a Gravity I2C interface for easy plug and play integration in to your projects. The build in LDO power management chip gives you a wide range of input voltages, from 5V. The on-board I2C level conversion also makes it compatible with and 5V devices. Compared to traditional ADXL345, The LIS2DH accelerometer has advantages such as extra stability and more efficient power consumption. Low power mode requires only 2uA, while normal mode requires 11uA. At maximum the module supports an output frequency of 5.3KHz. Sensitivity levels are adjustable to either +-2g, +-4g, +-8g or +-16g and the module supports 16-bit data outputs. There are 2 independent programmable interrupt generators for free-fall and motion detection, that will activate interrupt wake-up. This module has many potential applications including wearable tech, display orientation and impact recognition.
