GY-87 10DOF MPU6050 HMC5883L BMP180

The GY-87 is a 10-DOF (Degrees of Freedom) sensor board that combines three separate sensors:

1. MPU6050: A 6-DOF inertial measurement unit (IMU) with a 3-axis accelerometer and 3-axis gyroscope. It measures linear acceleration and angular velocity.
2. HMC5883L: A 3-axis digital compass that measures the Earth’s magnetic field. It can be used to determine the direction of North.
3. BMP180: A digital barometric pressure sensor that measures atmospheric pressure. It can be used to determine altitude.

Key features and applications of the GY-87:

• Orientation and attitude sensing: The combined data from the accelerometer, gyroscope, and compass can be used to determine the orientation and attitude of a device in 3D space.
• Motion detection: The accelerometer and gyroscope can be used to detect motion, such as shaking, tilting, or rotation.
• Altitude measurement: The barometric pressure sensor can be used to measure altitude, which is useful for drones, robots, and other applications that need to know their height above ground level.
• Navigation: The compass and accelerometer can be used for basic navigation, such as determining the direction of North and detecting changes in heading.

Common uses of the GY-87:

• Robotics: For controlling the movement and orientation of robots.
• Drones: For navigation, stabilization, and altitude control.
• Wearable devices: For fitness tracking, activity monitoring, and gesture recognition.
• Virtual reality: For tracking the user’s head movements and orientation.
• Augmented reality: For overlaying digital information on the real world.
