传感器在自动控制、信息处理、遥测、遥控技术中担负着信息采集任务,传感器能将我们想探测或调控的物理量转换成便于测量和调节的量,大多转变为电学量(电流、电压等),当待测物理量变化时,电路中的电流或电压也按照相应规律变化,我们测电流或电压就可知道待测物理量的变化,调控电流或电压也可以反过来对原物理量进行调控.传感器为自动测量、自
The sensors are responsible for information acquisition tasks in automatic control, information processing, telemetry, and remote control technologies. The sensors can convert the physical quantities that we want to detect or control into quantities that can be easily measured and adjusted, and most of them are converted into electrical quantities (current, voltage, etc.). When the physical quantity to be measured changes, the current or voltage in the circuit also changes according to the law. We can know the change of the physical quantity to be measured by measuring the current or voltage, and the regulation of the current or voltage can also in turn regulate the original physical quantity. The sensor is automatic. Measurement, self
