Test equipment
The Adafriuit 10 DOF IMU (in figure 3) is used for measuring the acceleration, rotation rate, heading,
pressure, temperature and altitude. The breakout board allows you to capture distinct types of motion
or orientation related data.
This IMU consists of 3 types of chips as,
LSM303DLHC - a 3-axis accelerometer (up to +/-16g) and a 3-axis magnetometer (up to+/-8.1 gauss)
L3GD20 - a 3-axis gyroscope (up to +/-2000 dps)
BMP180 - A barometric pressure sensor (300..1100 hPa) that can be used to calculate altitude, with an
additional on-board temperature sensor
