Environmental monitoring describes the processes and activities that need to take place to characterize and monitor the quality of the environment. Substantial part of these activities are remote surveillance and remote sensing of air, water and soil quality.Air quality measurements include concentration of pollutants as ozone, fine particulate matter (PM), nitrogen dioxide, sulphur dioxide, carbon monoxide, total reduced sulphur compounds, etc. In most countries Air Quality Standards are set on the concentration limits of these pollutants. Monitoring of weather is also critical in terms of understanding pollutant formation, dispersion, transport and removal.Impact measurements in rivers and lakes provide data on parameters such as pH, dissolved oxygen, conductivity, turbidity, color, etc. Semi-continuous and continuous monitoring premises equipment with programmable sampling at fixed or variable time intervals or in response to an external trigger, e.g. from a rain gauge.The sustainable use of soil resources depends on three factors: soil characteristics, related environmental (climate, hydrologic, etc.) conditions and land use. These factors interact on a systems-based principles, where the change in one factor causes alteration in the others. Soil quality and sustainability evaluation includes measurements of soil moisture, electrical conductivity, temperature, dielectric permittivity, etc. The common objective is to optimize analysis of soil conditions for enhanced quality and yield of turf and crops.
The unattended and remote nature of most environmental measuring and monitoring stations implies the need to operate from a DC power source, such as a battery. In some cases remote sensing stations make it possible to collect data on dangerous or inaccessible areas.Infinite offers maintenance free solutions for movable remote measurement stations, based on the ADU-500 and BSC-50E battery powered RTU/data loggers. Particularly ADU-500 supports data collection from a wide range of environmental sensors, based on the SDI-12 protocol.iLOGPlus-GSM RTU/Data Logger supplied from a rechargeable battery combined with a solar cell, can be applied in applications demanding several measurement channels and real time data monitoring. Both solutions combine reliability in harsh environmental conditions with the flexibility of wireless telemetry.
