The statistical analysis method of telemetry data of wireless smart sensors and actuators, which are designed for the measurement of the thermodynamic parameters and consumption control of energy sources, was developed as a result of carried investigations. Statistical analysis of telemetry information allows to determine the status of the device being analysed, make conclusion about its operation...
Wireless measurement systems will provide significant benefits to industrial applications, for production facilities as well as in mobile or R&D scenarios. However, in order to exploit the improvements by flexibility, scalability and easy reconfigurability brought by wireless sensor networks (WSN), industrial use cases often require a sustainable autonomous energy supply, while providing the reliability...
Patients with severe health problems often require permanent monitoring using low-power devices for a modern superior medical care.

Healthcare applications based on WSN are gaining high popularity all over the world due to their features like flexibility, mobility and ease of constant monitoring of the patient. The main focus of such system is remote monitoring of patient, inside and outside the hospital room and in ICU.
Monitoring Wireless Sensor Networks (WSNs) are composed of sensor nodes that report temperature, relative humidity, and other environmental parameters. The time between two successive measurements is a critical parameter to set during the WSN configuration because it can impact the WSN's lifetime, the wireless medium contention and the quality of the reported data. As trends in monitored parameters...
The goal of this paper is to present a scenario that optimizes a passive RFID data transmission without changing its standard. This procedure is based on the inventory process defined by the EPC Gen 2 protocol. An application of this procedure will be presented through a wireless temperature sensor concept and an ASIC implementation.
Wireless sensor networks (WSNs) have been adopted as merely data producers for years. However, the data collected by WSNs can also be used to manage their operation and avoid unnecessary measurements that do not provide any new knowledge about the environment. The benefits are twofold because wireless sensor nodes may save their limited energy resources and also reduce the wireless medium occupancy...
Living conditions in any country are important, especially a local environment is more important to many people. The parameters like a noise level, light intensity, barometric pressure, carbon monoxide (CO) and carbon dioxide (CO2) concentration levels are monitored to evaluate living conditions. The mentioned reasons led to the practical realization of Wireless Unit for Environmental Monitoring (WUEM)...
The wireless sensor network (WSN) represent a fertile area for research and exploration, especially with the enormous development in modern electronic systems, where it becomes an alternative to traditional wired systems. The wireless systems are less energy-consumptive and inexpensive, in addition, it helps to reduce the complexity of wiring. Wireless sensor networks require the design of high density...
