Grove 3-Axis Digital Accelerometer(LIS3DHTR) is a low-cost & power-saving 3-Axis accelerometer in a bundle of Grove products. It is based on the LIS3DHTR chip which provides multiple ranges and interface selection. You can never believe that such a tiny 3-Axis accelerometer can support I2C, SPI, and ADC GPIO interfaces, which means you can choose any way to connect with your development board. This accelerometer can also monitor the surrounding temperature to tune the error caused by it.
It has dynamically user-selectable full scales of ±2g/±4g/±8g/±16g and is capable of measuring accelerations with output data rates from 1 Hz to 5.3 kHz.
