<P>PROBLEM TO BE SOLVED: To provide an acceleration detection method and its device capable of detecting highly accurately an acceleration in the whole range used as a detection object, and an acceleration sensor module and a tire. <P>SOLUTION: This acceleration detection device 100 has a constitution equipped with an insulating substrate 101, and two acceleration sensors 110A, 110B, a control IC 200 and a power source part 300 arranged on the substrate 101. Each of the two acceleration sensors 110A, 110B has a detectable range wherein the maximum acceleration value detectable in an allowable error range of ±1% is an upper limit and the lowest acceleration value is a lower limit value, and the detectable range of each acceleration sensor 110A, 110B is set to be different having at least a range not mutually overlapping partially. A detection object from a low acceleration to a high acceleration is detected with an accuracy in the allowable error range by using the acceleration sensors 110A, 110B. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
