Methods for constructing optimal spatial sampling designs for environmental monitoring networks, widely applied in a large number of disciplines, generally produce static designs that are optimal under models with no explicit temporal structure. However, environmental processes tend to exhibit both spatial and temporal variability; hence, static networks may not capture the essential spatiotemp...

We present a distributed algorithm for environmental monitoring of a scalar field (such as temperature, intensity of light, atmospheric pressure, etc.) using a random sensor network. We derive an error estimate, discuss the average complexity of the algorithm, and present some simulation results.

An important step towards reducing humankind’s reliance on unsustainable energy is by improving energy efficiency in a home or building. One solution to energy-intensive homes is to take environmental measurements in-house that can alert the owner of what rooms and conditions have high-energy waste (e.g., unnecessary air-conditioning or lighting). This paper describes the development and perfor...

Citizen science is quickly becoming one of the most effective tools for the rapid and low-cost collection of environmental information, filling a long recognized gap in in-situ data. Incentivizing citizens to participate, however, remains a challenge, with gaming being widely recognized as an effective solution to overcome the participation barrier. Building upon well-known gaming mechanics, ga...

A data logger is an electronic instrument that records environmental parameters such as temperature, relative humidity, wind speed and direction, light intensity, water level and water quality over time. Typically, data loggers are compact, battery-powered devices that are equipped with microprocessor input channels and data storage. Most data loggers utilize turnkey software on a personal comp...

Environmental monitoring of environmental pollution prevention and control in humans to resolve existing or potential environmental problems and improve the living environment and the ecological environment, coordinating the relationship between human beings and the environment, and ultimately to sustainable human development plays an important role. In order to accurately and fully grasp the p...

Toxic chemicals introduced into the environment can penetrate ecosystems and can be found in the whole biosphere. Chemical contamination may affect ecosystems, causing changes in the functions of particular organisms. Adverse effects of xenobiotics and their metabolites on living organisms can be observed. In the last few years investigations have focused on searching for bioindicators (both pl...

Fairly rapid environmental changes call for continuous surveillance and on-line decision making. There are two main areas where IT technologies can be valuable. In this paper we present a multi-agent system for monitoring and assessing air-quality attributes, which uses data coming from ameteorological station. A community of software agents is assigned to monitor and validate measurements comi...

A sensor network data gathering and visualization infrastructure is demonstrated, comprising of Global Sensor Networks (GSN) middleware and Microsoft SensorMap. Users are invited to actively participate in the process of monitoring real-world deployments and can inspect measured data in the form of contour plots overlayed onto a high resolution map and a digital topographic model. Users can go ...

The use of microsensors for in-field monitoring of environmental parameters is gaining interest due to their advantages over conventional sensors. Among them microsensors based on semiconductor technology offer additional advantages such as small size, robustness, low output impedance and rapid response. Besides, the technology used allows integration of circuitry and multiple sensors in the sa...
