Actuators & Sensors in Mechatronics: Introduction to Sensors K. Craig 6
• Note
– The distinction among monitoring, control, and analysis functions is not clear-cut; the category decided on may depend somewhat on your point of view and the apparent looseness of the classification should not cause any difficulty. – It is now extremely common for engineers to include in the design of a machine or process, as dedicated components, computers of various sizes. Computers are important, but the computer “component” of many machines and processes is often not the critical system element in terms of either technical or economic factors. Rather, components external to the computer, the actuators and sensors, are more often the limiting factors in the system design.

Sound waves make the microphone electret film （驻极体膜） vibration [vaɪ'breɪʃ(ə)n], result in the change of capacitance [kə'pæsɪt(ə)ns], and produce with the corresponding change of tiny voltage ['vəʊltɪdʒ; 'vɒltɪdʒ]. Then this voltage is converted into 0 to 5 voltage, and transmitted to the computer, after A/D conversion was accepted by the data collector.

Transducers, Sensors, and Actuators
Transducer: converts a signal from one physical form to a corresponding signal having a different physical form “energy converter” (mechanical, thermal, magnetic, electric, chemical, and radiation) Sensor: offering an electric output A sensor may not be a transducer. modifier Input transducers (physical signal/electric signal) are termed sensors, or detectors for radiation, output transducers (electric signal/display or actuation) are termed actuators or effectors.

1.4 Static aracteristics of Measurement Systems
Accuracy, Precision, and Sensitivity
Accuracy is the quality that characterizes the capacity of a measuring instrument for giving results close to the true value of the measured quantity. Sensor accuracy is determined through static calibration. It consists of keeping constant all sensor inputs, except the one to be studied. Error: Any discrepancy between the true value for the measured quantity and the instrument reading. Absolute error: the difference between measurement result and the true value.

二极管。 • 发光部件主要是发光二极管，可以将电能转化为光能。只要电路

• 湿度传感器由敏感元件和转换电路组成。当环境湿度发生变化时， 湿度传感器的敏感元件产生相应的变化，传感器的转换电路把敏 感元件的变化量转换成电压量变化，对应于相对湿度0～100%RH 的变化，传感器的输出呈0～1v的线性变化。
• 下面我们通过Dht11，串口通信和IF开发板为大家做一个简单的演 示。
S = V·△t /2 这就是所谓的时间差测距法。由于超声波也是一种声波, 其声速C与温度有关,表1 列出了几种不同温度下的声速。在使用时,如果温度变化不大, 则可认为声速是基本不变 的。常温下超声波的传播速度是334 米/秒,但其传播速度V 易受空气中温度、湿度、压 强等因素的影响,其中受温度的影响较大，如温度每升高1 ℃, 声速增加约0. 6 米/ 秒。 如果测距精度要求很高, 则应通过温度补偿的方法加以校正。已知现场环境温度T 时, 超声波传播速度V 的计算公式为： V = 331.45 + 0.607T
• 下面我们就来用串口通信来探究一下吧。

按测量目分类 物理型传感器是利用被测量物质的某些物理性质发生明显变化的特性制成的。 化学型传感器是利用能把化学物质的成分、浓度等化学量转化成电学量的敏感元件制 成的。 生物型传感器是利用各种生物或生物物质的特性做成的，用以检测与识别生物体内化 学成分的传感器。 按其构成分类 基本型传感器：是一种最基本的单个变换装置。 组合型传感器：是由不同单个变换装置组合而构成的传感器。 应用型传感器：是基本型传感器或组合型传感器与其他机构组合而构成的传感器。 按作用形式分类 按作用形式可分为主动型和被动型传感器。 主动型传感器又有作用型和反作用型，此种传感器对被测对象能发出一定探测信号， 能检测探测信号在被测对象中所产生的变化，或者由探测信号在被测对象中产生某种 效应而形成信号。检测探测信号变化方式的称为作用型，检测产生响应而形成信号方 式的称为反作用型。雷达与无线电频率范围探测器是作用型实例，而光声效应分析装 置与激光分析器是反作用型实例。 被动型传感器只是接收被测对象本身产生的信号，如红外辐射温度计、红外摄像装置 等。
