    摘要: A pressure sensor is provided which is tolerant to noise such as electromagnetic waves, is configured so as to be capable of easily selecting a system environment in which a sensor signal, commonly used for various kinds of systems, can be freely read in at timing as required by a system, and is able to realize reduction in size and cost suitable for automotive use. An element portion for detecting pressure and a circuit portion having a signal processing function are integrally accommodated in the same package. An interface section 24 optimized to interface with external wiring, an A/D conversion section 25 for digitally encoding an analog processed detection signal of the sensor, and a digital processing section 26 for converting the digitized signal into a desired serial signal are added to the circuit portion 2. The entire circuit portion is constituted by at most two ICs alone, and a selection can be made between two output forms including an analog processed detection signal and a digital processed detection signal.

    摘要: A tilt sensor, height sensors and tire pressure sensors sense a behavior of a parked vehicle and output an angle signal, a height signal and a pressure signal, respectively. These sensor signals are obtained by a sensor signal obtaining section. An initial value setting section sets an initial sensor signal of each of the tilt sensor, the height sensors and the tire pressure sensors as an initial value of that sensor. Then, a comparing section compares each initial value with the current sensor signal. Based on a result of the comparison, a determining section determines whether the vehicle is stolen.
