Gravity - LIS2DW12 - 3-axis accelerometer ±2g/±4g/±8g/±16g - I2C - DFRobot SEN0409

Gravity module in a form of 3-axis accelerometer, which allows to measure linear acceleration. It has a built-in LIS2DW12 chip (belonging to the popular LIS series) and is powered by a voltage in the range of 3.3 V to 5 V. Additionally, the sensor from DFRobot has the ability to measure acceleration in the range of ± 2 g / ± 4 g / ± 8 g / ± 16 g. The measurement frequency ranges from 1.6 Hz to 1600 Hz.

Gravity - LIS2DW12 - 3-axis accelerometer included with dedicated connection cable.

Connection of accelerometer with Firebeetle-M0 board using Gravity connector.

The module has a Gravity compliant connector. Thanks to it there is no need to solder additional connectors, and whole connection process is much faster and more comfortable.

Accelerometer is a sensor that allows to determine selected body parameters. We're talking about acceleration measurement (in three axes), so the term accelerometer is used interchangeably. Accelerometer is a transducer that measures linear acceleration, that is, it measures its own motion. Not sure where an accelerometer is used? It's easy - you can even find one in your mobile phone.
