The objective of this paper is to present a highly customizable wireless monitoring solution for monitoring of environment characteristics, to evaluate propagation characteristics of wireless signal in inhabited buildings and to discuss important aspects of wireless monitoring systems. We have designed home monitoring system that uses ZigBee wireless sensor network with 8-bit microcontrollers and...
A new multi-protocol wireless measurement system applicable for smart households is presented in this paper. The system is based on a multi-standard wireless concept that by employing so-called RF network combiner can offer the interoperability of several protocols/networks. The main goal is monitoring several different parameters and processes by utilizing a multiplex oriented management software...
This paper proposes a radio frequency (RF) energy harvesting system which enables scavenging energy from an electromagnetic far field. The system consists of a quarter-wave monopole antenna, a matching circuit, an energy conversion module, an energy storage capacitor, a low-power comparator and a DC-to-DC converter. The RF energy harvester operates at a frequency band of 868 MHz and creates a pulsed...
Wireless communication technologies together with physiological signals sensing provide a wide range of capabilities for monitoring, recording and analysis of the physical and health status of individuals. This paper describes two systems using wireless transmission of information designed to measure physiological signals. The first system is system for automatic cardiopulmonary examination measuring...
