Abstract: The main goal is to solve the trade-off between the need for performing the real laboratory in engineering students and the real time analysis the sensors characteristic in the industries, the rapid development in the research and innovation field was supposed to ease the workload of scientists and engineer. As more and more sensors/transducers are being introduced in the market, engineers are having trouble to pick the best suited sensor for the application, hence the sensors and the signal conditioning circuit are the main part and are discussed in this paper. Writing firmware for the controllers so as to read the specific characteristics is also very important task. The fast popularization of embedded Advanced RISC (Reduced instruction set computer) Machine (ARM) processor, it has been a trend that ARM processor can substitute the single-chip to realize data acquisition and control. A new kind of input/output portable instrumentation lab on embedded ARM platform has been researched and developed in this paper, whose hardware platform use 32-bit embedded ARM microprocessor, and software platform use the GNU and the compiler use the win-ARM. In the existing instrumentation labs with different interfacing card are required for different transducers. In Moreover all instrumentation labs, are using personal computer for output analysis, so dedicated software are required for different sensors, for study, compare and detection of sensor. So in all complexity and setup area increases and hence portability decreases.
