Gravity: BNO055+BMP280 Smart 10DOF AHRS & IMU Sensor - SEN0253

Gravity: BNO055+ BMP280 Intelligent 10DOF AHRS & IMU Sensor - SEN0253 is a package system that integrates a three-axis 14-bit accelerometer, a three-axis 16-bit gyroscope, a three-axis geomagnetic sensor and a 32-bit microcontroller. The BNO055 can provide not only single data of three types of sensors (accelerometer/gyroscope/geomagnetic), but also combined data such as quaternions, Euler angles or vectors. In addition, the built-in MCU frees users from the complexities of algorithm processing, which can lead to a smartphone, wearable device, etc. it provides application support for many aspects.

The BMP280 is an absolute barometric pressure sensor designed specifically for mobile applications that can measure barometric pressure and temperature (data can be converted to altitude via a specific formula). The sensor module is located in an extremely compact package. It is based on Bosch's proven Piezo-resistive pressure sensor technology and has high accuracy and linearity, as well as long-term stability and high EMC robustness. A large number of device operation options offer the highest flexibility to optimize the device in terms of power consumption, resolution and filter performance.
