... BMA145 features 3.1 General description The BMA145 is a fully calibrated, triaxial low-g analog acceleration sensor. It allows measurements of static as well as dynamic accelerations in all three dimensions. Due to its three perpendicular axes it gives the absolute orientation in a gravity field and enables free-fall detection. The sensor is set two-chip arrangement consisting of a three-channel capacity differential MEMS acceleration-sensing element and an application specific integrated circuit (ASIC) ...
