An intelligent wireless smart sensors leak into many branches in technical diagnostics recently. Need of measurement a record various quantities is still rising. Main focus is aimed to energy saving houses, to large complex with many air conditioning units, to industry, where is need of simple action intervention on many places. Problem coming up, when the building has no sufficient cable infrastructure...
This article contains a short presentation of an improved system for environmental monitor and control in terms of efficiency, performance and flexibility. The main topics cover: the basic concepts of the system, the implementation characteristics and the standards of performance. In the end, the advantages and disadvantages of this system are pointed, along with some future development guidelines.
Wireless sensor network technology emerged in recent years with numerous potential applications. The building environment and energy monitoring (BEEM) is among the most important ones. The design of such smart wireless sensing system is presented in this paper. The proposed system consists of low power Tyndall wireless sensor node hardware with light energy harvesting featured power supply and energy...
Corrosion of aircraft and rotorcraft costs the US military billions of dollars annually, and is by far the largest single maintenance cost driver for Navy and Marine Corps airframes. The various forms of localized corrosion, such as pitting corrosion, crevice corrosion, exfoliation, and environment assisted cracking, are particularly destructive and frequently occur without any outward signs of damage...
The paper presents a development of the multi sensor embedded system for measuring up to eight sensor parameters optimized by appropriate algorithms. Since most of the industrial applications use the analog sensors with transmitters for sensing the process parameters particularly in harsh environment because of their strong mechanical packaging and ruggedness. Then the benefits of digital technology...
The paper presents the interface designed for wireless data and power transmission. The interface operation idea was tested using build up hardware and software. The sample construction of the temperature sensor embedded with this type interface was designed. Measurements show that the sensor can be wirelessly supplied with energy and is capable to sent data (temperature readings) in 5 cm distance...
On the basis of the Programmable System-on-Chip (PSoC) and thin-film MEMS structure the Smart Pressure Sensor was developed by using newest method of definition of gas pressure. This sensor have such advantages before analogues as high accuracy of transformation, stability of characteristics, durability, presence of a set of standard digital and wireless interfaces. On the basis of one chip PSoC all...
This paper presents a low-cost tide measurement system based on a set of two inclinometers. The inclination sensors deliver a DC output voltage which varies linearly with the angle of its working direction. Thus, with two inclinometers assembled in orthogonal directions, it is possible to provide the tide direction and intensity. The tide measurement system was developed for a stand alone operation...
