For the research purpose, we are focusing on a high variable parameter (vibration of a cable car element) and on a Design constrains low variable (ambient temperature). The real time measurement Using MEMs sensors means low level of voltage, low up system is implemented with a wireless low data transmission rate, to ultra-low power supply requirements, voltage level and the main target is to optimize the entire process from the adapting, and protocol’s conversion (serial with many data energy consuming point of view. We have used two different low level protocol, different media converters, physical level power transceivers on ISM band, we optimized acquisition conversions). procedures, and on the processing point we have recovered the parameters variations. With a high speed current probe we They are some real examples of measurements which are measured the power consumption on both cases, and based on characterized by large amount of data, different sampling dedicated communication protocols we have estimated the periods, different data communication systems, and different consumed energy per bit for the power supply evaluation in processing requirements. Even they are not very fast, the wireless monitoring system. mentioned characteristics are contradictory from the designer point of view. This paper is focused on developing a Keywords— transportation monitoring, DAQ, wireless sensors, microcontroller- based algorithm dedicated to support sensor optimization, energy per bit, data recovery system.

On transducers and measurements are the core role for them. In this context, electronic datasheet (TEDs) standard, few TEDS variants have the correct evaluation of measurement uncertainty leads to the been developed, and they are not covering many variations of definition of the confident interval of the measurement values. attributes yet. Even se define the largest list of attributes, it is Based on measurement systems structures, some of very hard to put data together in the same table. In the uncertainties might come from different component blocks database and measurement theory, the concept of arranging (input ports, conditioners, ADC, processing, communication). and accessing data in memory is called data alignment. Because of different parameters attributes, data have to be When some new/or emergency functions are added to the stored into memory as multiple of words sized, in order to device, like self-configuration, self-compensation, or sensor simplify memory access description.

Welcome to the world of PCB designing, where you will not only learn but update yourself with various advance technologies and designing tips. First of all, let us see the basic of PCB Designing step by step, which will give you an idea what exactly PCB designing is? First step is schematic capture or schematic entry is done through an EDA (Electronic Design Automation) tool. Card dimensions and template are decided based on required circuitry and case of the PCB. Determine the fixed components and heat sinks if required. Deciding stack layers of the PCB. 4 to 12 layers or more depending on design complexity. Ground plane and Power plane are decided. Signal planes, where signals are routed, are in top layer as well as internal layers. Line impedance determination using dielectric layer thickness, routing copper thickness and trace-width. Trace separation also taken into account in case of differential signals. Microstrip, stripline or dual stripline can be used to route signals. Placement of the components. Thermal considerations and geometry are taken into account. Vias and lands are marked. Routing the signal trace. For optimal EMI performance high frequency signals are routed in internal layers between power or ground planes as power plane behaves as ground for AC. And the last step Geber File generation for manufacturing.
