EFFECTIVE LOW-COST AREAWIDE WATER QUALITY MONITORING

PILS: Low-Cost Water-Level Monitoring

Cost-Effective Sampling of Ground Water Monitoring Wells

Cost-Effective Sampling (CES) is a systematic methodology for estimating the lowest-frequency sampling schedule for a given groundwater monitoring location which will still provide needed information for regulatory and remedial decisionmaking. Its initial development at Lawrence Livermore National Laboratory (LLNL) was motivated by our desire to have a systematic argument to reduce sampling fre...

Low Cost UAV-based Remote Sensing for Autonomous Wildlife Monitoring

In recent years, developments in unmanned aerial vehicles, lightweight on-board computers, and low-cost thermal imaging sensors offer a new opportunity for wildlife monitoring. In contrast with traditional methods now surveying endangered species to obtain population and location has become more cost-effective and least time-consuming. In this paper, a low-cost UAV-based remote sensing platform...

Effective Calibration of Low-Cost Soil Water Content Sensors

Soil water content is a key variable for understanding and modelling ecohydrological processes. Low-cost electromagnetic sensors are increasingly being used to characterize the spatio-temporal dynamics of soil water content, despite the reduced accuracy of such sensors as compared to reference electromagnetic soil water content sensing methods such as time domain reflectometry. Here, we present...

Low-cost robotic sensor networks platform for air quality monitoring

Building robotic sensor networks (RSNs) for air quality monitoring application is a challenging frontier for robotic research. Such systems must operate for extended periods of time in unstructured and complex domains. The implementation requires addressing numerous issues at the systems level such as energy efficiency, planning, and controlling robots’ trajectories for achieving robust operati...
