Environmental protection is one of the most challenging tasks for humanity. All of the latest technologies to certain extent are applied in this area, among others, wireless sensor networks as well. In this paper a wireless sensor node designed specifically for monitoring of environmental parameters is described. The main advantage of this node is the use of energy harvesting techniques and supercapacitor...
In order to achieve better collecting consumption, diagnostic and status of water, natural gas and electricity metering, an electronic device known as smart meter is introduced. These devices are increasingly installed around the globe and together with Automatic Meter Reading (AMR) technology form the basis of future intelligent metering. Devices known as concentrators collect consumption records...
As the effects of global warming are spreading globally, the world population encounters one of the most important social and scientific phenomena-changing the parameters of the environment due to pollution. Any conducted action requires precise and accurate measuring of the environmental parameters at several dozens of thousands points deployed around the world. Since financially, as well as practically,...
Specific requirements in the design of modern electronic devices have increased popularity of flexible printed circuits. In recent years, with the application of new materials and their printing on a flexible substrate, a large number of new flexible sensors have been developed. In this paper, the implementation of a device made by ink-jet printing on a flexible substrate is described. Fully flexible...
Monitoring of surface water areas before, during and after the flood is important to collect useful information for future risk assessment and for the purpose of learning about future preventive measures. This paper describes the development of the wireless sensor network (WSN) node capable of collecting water level measurement data on remote locations that are covered by surface waters, either by...
This paper describes a modern system for measuring the concentration of gases. Industrial processes can be a source of pollution and population should be promptly informed of any change in the concentration of harmful gases. Unlike industry, gases that are produced in landfills is impossible to avoid due to natural processes and general tendency is to use gas emissions as an energy source (natural...
This paper describes a modern GPRS based system for air pollution monitoring. Due to the widespread of the mobile telephony, currently it is possible to use GPRS modules for wireless data acquisition and control. At the moment, there are a lot of available solutions with usage of GPRS modems and some of them are mentioned in this paper as reference to our design. Explanations of how to use GPRS modem...
This paper describes one solution for air quality monitoring where data are collected via RF wireless communication in public frequency band. This solution uses low-cost RF modules and encrypted data transmission for minimization annual maintenance cost which is a huge disadvantage with GPRS systems. Low-cost gas sensors provide alarm functioning of the system, but basic information about monitored...
