<P>PROBLEM TO BE SOLVED: To provide an acceleration sensor module unaffected by noise in a power source voltage even in cases where a clock is utilized for converting capacitance into a voltage since a sensor part is of a capacitance type. <P>SOLUTION: This acceleration sensor module comprises: a sensor part 30 including a capacitance type detection part 32 mounted on a front part and/or a side part of a vehicle for detecting acceleration of the vehicle and a conversion part 34 for converting capacitance into a voltage; and an adjustment part 40 including an AD converter 46 for AD-converting an output of the conversion part, a communication circuit 48 for sending the output of the AD converter to a collision determination part, a power source part 42 for supplying electric power to the AD converter, to the communication circuit, and to the sensor part, and an oscillator 44 for supplying a clock to the AD converter and to the conversion part of the sensor part. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
