一种基于微机的传感器自动调零电路

Microcomputer-based Automatic Zero Adjustment Circuit for Sensor

为了解决所有传感仪表都必须考虑的零点漂移问题,提出了一种基于单片机(微机)控制,使用模数转换器实现传感器自动调零的方法,并给出了硬件设计电路。实验表明,该方法能够快速有效地实现仪表系统的自动调零。

The zero drift is a problem that has to be considered for all the sensing instruments. A method based on single chip microcomputer （computer） control and realized by ADC to achieve automatic zero adjustment of a sensor is put forward. The hardware design circuit is offered. Experiments show that the method can achieve fast and effective automatic zero of instrument systems.
