DFRobot Gravity 10DOF module with intelligent orientation sensor BNO055 and BMP280 pressure

Description

Gravity BNO055 + BMP280 intelligent 10DOF AHRS is a 10DOF module with an intelligent orientation sensor BNO055 (accelerometer, gyroscope and magnetometer + microcontroller) and a BMP280 pressure sensor equipped with a Gravity connector.

BNO055 is a system used to implement the intelligent 9-axis absolute orientation sensor. It is an integrated three-axis 14-bit accelerometer, a three-axis 16-bit gyroscope, a three-axis geomagnetic sensor and a 32-bit microcontroller. It provides not only single data from three types of sensors (accelerometer / gyroscope / magnetometer), but also integrated data, such as quartered, Euler angles and vectors. In addition, the built-in MCU relieves the processing of complex algorithms, which facilitates application support in many aspects for smartphones or mobile devices.

BMP280 is an absolute barometric pressure sensor, specially designed for mobile applications that can measure atmospheric pressure and temperature. The sensor module is placed in an extremely compact package. It is based on proven technology of resistive pressure sensors from Bosch, characterized by high accuracy and linearity as well as long-term stability and high resistance to electromagnetic interference.
