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.

Acoustic sensors(声敏传感器)
Working principle
The sensor is sensitive to a built-in to sound capacitive [kə'pæsɪtɪv] electret microphone（电容式驻极话筒）. 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.

• 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

For (2.1) to be valid, if the potentiometer is supplied by an alternating voltage, its inductance and capacitance should be insignificant. For low values of the total resistance RT, the inductance may be significant, particularly in models with wound resistive elements. For high values of RT, the parasitic capacitance may be important. Furthermore, resistors drift with temperature. Temperature changes can arise not only from fluctuations in ambient temperature but also from selfheating due to the finite power that the potentiometer dissipates. Friction and inertia of the wiper also limit the model validity. Finally, noise associated with the wiper contact limits resolution.
Therefore for small variations, the resistance of the metallic wire is

When a semiconductor is stressed, in addition to its dimensional change, both the number of carriers and their average mobility change. Unlike metals,the resistivity change under stress dominates over the dimensional change.

Methods for resistance measurement can be classified into deflection methods or null methods. Deflection methods sense the drop in voltage across the resistance to be measured or the current through it or both. Null methods are based on measurement bridges.

Once the balance condition has been achieved we have
That is, changes in R3 are directly proportional to the corresponding changes we have to produce in R4 in order to balance the bridge. This measurement method can be also used as a polarity detector because the output is positive or negative, depending on whether x is greater or less than a given threshold.

Figure 3.17(a):
Wires 1 and 3 must be equal and undergo the same temperature changes. The characteristics of wire 2 are irrelevant because in the balance condition there is no current through the bridge central arm.
