国外的传感器及敏感器件过去是由单一的非电量测量,现在已逐步地向由大规模集成电路构成的计算机、微处理机为中心的完整的自动控制系统过渡。传感器及敏感器件将环境的参量如:温度,湿度、照度、机械应力、加速度、磁场、气压、有毒气体含量等非电量参量转化为电量参量,经放大交给计算机及微处理机处理,然后反过来控制这些参量,从而达到自动控制的目的。

Foreign sensors and sensitive devices used to be a single non-power measurement in the past, and now it has gradually transitioned to a complete automatic control system consisting of a large-scale integrated circuit computer and a microprocessor. Sensors and Sensitive Devices The parameters of the environment such as temperature, humidity, illumination, mechanical stress, acceleration, magnetic field, barometric pressure, toxic gas content and other non-electrical parameters are converted into electrical parameters, which are then sent to computers and microprocessors for amplification. Come to control these parameters, so as to achieve the purpose of automatic control.
