10 DOF IMU Sensor, Low Power

10 DOF IMU Sensor (B) is good at motion monitor, as well as detecting/measuring the position, height, and temperature. It would be helpful for making your own copter or balancing robot, provides great man-machine interaction.

Features

  • MPU9255 : 3-axis gyroscope, 3-axis accelerometer, and 3-axis compass/magnetometer
  • Internal Digital Motion Processing™ (DMP™) engine, offloads complicate fusion calculation, sensor synchronization, gesture recognition, etc.
  • Comparing with MPU6050, the MPU9255 is lower power consumption, and more suitable for wearable devices
  • BMP180 : barometric pressure sensor
  • Embedded temperature sensor for temperature compensation
  • You can get the 10 DOF data through I2C interface
