　　1、内容需求的提高

　　接近传感器 检测到几乎没有任何接触点的物体的存在。由于传感器与被测物体之间没有接触，没有机械部件，因此这些传感器使用寿命长，可靠性高。接近传感器的不同类型是电感式接近传感器、电容式接近传感器、超声波接近传感器、光电传感器、霍尔效应传感器等。接近传感器发射电磁场或静电场或电磁辐射束（如红外线），并等待返回信号或现场变化。被感测的物体被称为接近传感器的目标。

　　传感器技术

　　最重要的先进和常见的传感器技术之一是 条形码识别. 市场上销售的产品有一个通用产品代码 (UPC)，它是一个 12 位代码。其中五个数字表示制造商，其他五个表示产品。前六位数字由代码表示为亮条和暗条。个数字表示数字系统的类型，第二个数字是奇偶校验位，表示读数的准确性。其余六位数字由代码表示为与前六位数字顺序相反的暗条和亮条。条码阅读器即使不了解标准码也可以管理不同的条码标准。制造组件的电磁识别类似于条形码技术，其中数据可以在磁条上进行编码。使用磁条，即使代码被油脂或污垢隐藏，也可以读取数据。

　　另一个重要的传感器设备是 与汽车有关的转发器。在汽车领域，很多情况下使用射频设备。应答器隐藏在钥匙的塑料头内，任何人都看不到。钥匙插入点火锁芯。当您转动钥匙时，计算机会向应答器发送无线电信号。在应答器响应信号之前，计算机不会让发动机点火。这些转发器由无线电信号供电。

　　表面声波 类似于射频识别。在这里，与射频系统相比，部件识别由雷达类型信号触发，并在长距离上传输。

　　光学字符识别 是一种使用字母数字字符作为信息来源的自动识别技术。在美国，光学字符识别用于邮件处理中心。它们还用于视觉系统和语音识别系统。

　　全球范围内提供传感器产品的公司。

　　Proximity sensor detects the presence of objects that are nearly placed without any point of contact. Since there is no contact between the sensors and sensed object and lack of mechanical parts, these sensors have long functional life and high reliability. The different types of proximity sensors are Inductive Proximity sensors, Capacitive Proximity sensors, Ultrasonic proximity sensors, photoelectric sensors, Hall-effect sensors, etc. A proximity sensor emits an electromagnetic or electrostatic field or a beam of electromagnetic radiation (such as infrared), and waits for the return signal or changes in the field. The object which is being sensed is known as the proximity sensor's target.

　　Sensor Technology

　　One of the most important advanced and common sensor technology is Bar-code Identification. The products sold in the markets have a Universal Product Code (UPC) which is a 12 digit code. Five of the numbers signify the manufacturer and other five signify the product. The first six digits are represented by code as light and dark bars. The first digit signifies the type of number system and the second digit which is parity signifies the accuracy of the reading. The remaining six digits are represented by code as dark and light bars reversing the order of the first six digits. The bar code reader can manage different bar code standards even without having the knowledge of the standard code. Electromagnetic Identification of Manufactured Components is similar to the bar code technology where the data can be coded on magnetic stripe. With magnetic striping, the data can be read even if the code is concealed with grease or dirt.

　　Another important sensor device is Transponder which is related to automobiles. In the automobile section, Radio frequency device is used in many cases. The transponders are hidden inside the plastic head of the key which is not visible to anyone. The key is inserted in the ignition lock cylinder. As you turn the key, the computer transmits a radio signal to the transponder. The computer will not let the engine to ignite until the transponder responds to the signal. These transponders are energized by the radio signals.

　　Surface Acoustic Waves is similar to the RF identification. Here, the part identification gets triggered by the radar type signals and is transmitted over long distances as compared to the RF systems.

　　Optical Character Recognition is a type of automatic identification technique which uses alphanumeric characters as the source of information. In United States, Optical character recognition is used in mail processing centres. They are also used in vision systems and voice recognition systems.
