A smart transducer is an analog or digital transducer or actuator combined with a processing unit and a communication interface. As sensors and actuators become more complex they provide support for various modes of operation and interfacing. Some applications require additionally fault-tolerance and distributed computing. Such high-level functionality can be achieved by adding an embedded microcontroller to the classical sensor/actuator, which increases the ability to cope with complexity at a fair price. In the machine vision field, a single compact unit which combines the imaging functions and the complete image processing functions is often called a smart sensor. They are often made using CMOS, VLSI technology and may contain MEMS〔http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=6011700〕 devices leading to lower cost. They may provide full digital outputs for easier interface or they may provide quasi-digital outputs like pulse width modulation. ==Advantages== # Compact # Higher reliability # Lower cost # Can be done using existing cmos processes # Ease of use # electronic data storage # self indication # auto correction # auto display 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Smart transducer」の詳細全文を読む スポンサード リンク
