Description
The module from Grove series, designed for9-deegre inertial navigation (IMU). It acts as agyroscope, accelerometer and electronic compass.For all functions responsible are two chips -LCM20600andAK09918. LCM20600 is 6-axis motion sensor which consists of 3-axis gyroscope and 3-axis accelerometer, and AK09918 is 3-axis electronic compass with very sensitive Hall sensor (of 0.15 µT/LSB). This allows for 9-level navigation, that is:the angular rotation x/y/z, acceleration x/y/z and magnetic force x/y/z.
The product is fully compatible withArduino, the manufacturer provides detailed instructions of software and sample source codeon its website. The module has a software adjustable range of the gyroscope from 250 dps to 2000 dps and of accelerometer: from 2 g to 16 G.
