    • A sensor device includes a voltage-to-pulse-number converter having a timing controller. When power is supplied to the converter from a power circuit through a power line, a timer circuit inhibits itself from performing a control operation until operations of a sensor and an amplifier become stable. After a predetermined period of time has passed, the inhibition of the controls is canceled. Then, an analog-to-digital (A-D) conversion of an output of the amplifier by the A-D converter is performed. Subsequently, a counter counts down from a value obtained from the A-D conversion. When the output of the counter becomes 0, the operation of the counter is stopped. Clock signals used for the operation of the counter are input to the pulse output circuit which is enabled only when the counter operates. Thereby, the timing controller outputs to an event counter a pulse signal having a number of pulses proportional to an output of the sensor. The sensor device obtains high precision data. Further, the power consumption of the sensor device is reduced. Consequently, the load imposed on a microcomputer is lightened.
    • 传感器装置包括具有定时控制器的电压 - 脉冲数转换器。 当通过电力线从电源电路向转换器供电时,在传感器和放大器的操作变得稳定之前,定时器电路禁止其执行控制操作。 经过一段预定的时间后,控制的禁止被取消。 然后,进行A-D转换器的放大器的输出的模拟(A-D)转换。 随后,计数器从A-D转换获得的值倒数。 当计数器的输出为0时,计数器的操作停止。 用于计数器操作的时钟信号被输入到脉冲输出电路,该脉冲输出电路只有在计数器运行时使能。 由此,定时控制器向事件计数器输出具有与传感器的输出成比例的脉冲数的脉冲信号。 传感器装置获得高精度数据。 此外,传感器装置的功耗降低。 因此,施加在微型计算机上的负载减轻。
