GY80 Sensor IMU Multi Sensor Board contains the following sensors such as L3G4200D, ADXL345, HMC5883L and BMP085. The L3G4200D is a low-power three-axis angular rate sensor. ADXL345 is a 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16 g. The HMC5883L is a surface-mount, multi-chip module designed for low-field magnetic sensing with a digital interface and the BMP-085 is a digital pressure sensor which has high accuracy and long-term stability. The GY-80 module has a built-in regulator and logic converter to support 3.3V/5.0V microcontrollers with I2C Digital Interface. It provides highly accurate and stable sensor data.

IMUs (inertial measurement units) are useful for many projects such as self-balancing robots and quadcopters. As part of the quadcopter project, I will be sharing with you how I connect and use a 10DOF GY80 Arduino sensor, a popular Chinese-made IMU. This sensor uses an I2C connection with the Arduino. There are four sensors on this board: a gyroscope (L3G4200D), an accelerometer (ADXL345), a Magnetometer (HMC5883L) and a Barometer & Temperature sensor (BMP085). Like I said, this IMU is so popular, there are tons of documents and articles on the internet about it.
