Gravity - 9DOF sensor BMX160 + temperature and pressure sensor BMP388 - I2C- DFRobot SEN0252

Description: Gravity - sensor 9DOF BMX160 + temperature and pressure sensor BMP388 - I2C - DFRobot SEN0252.

The module is equipped with two BMX160and BMP388sensors. BMX160 is a 9-axis sensor which allows to measure the acceleration in the ranges ± 2 g / ± 4 g / ± 8 g / ± 16 g and the angular position (gyroscope) in the ranges from 125°/s to 2000°, while BMP388 is responsible for measuring temperature from 0°C to 65°C and atmospheric pressure from 300 hPa to 1250 hPa.

Module with sensors BMX160 and BMP388 - Grove cable and goldpin strips are also included.

The board is equipped with a Gravity connector, which makes it possible to connect it to the base plate in an easy way. Current demand is less than 1.5 mA. The module with this combination of sensors will be used in dronesandapplications for height, position and orientation measurement.
