The next generation of low-cost personal air quality sensors for quantitative exposure monitoring

Advances in embedded systems and low-cost gas sensors are enabling a new wave of low-cost air quality monitoring tools. Our team has been engaged in the development of low-cost, wearable, air quality monitors (M-Pods) using the Arduino platform. These M-Pods house two types of sensors – commercially available metal oxide semiconductor (MOx) sensors used to measure CO, O3, NO2, and total VOCs, a...

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...

Low-Cost Airborne Thermal Sensors for Animal Monitoring

Background Vertebrate pests are a major environmental and economic threat in New Zealand. One of the species that has high potential threat is possum (Trichosurus vulpecula). The direct environmental impacts of possum are in defoliation of native flora and predation of native birds (Montague 2000). The direct economic impact is a result of their role as vectors of bovine tuberculosis (Tb). New ...

Design and Deployment of Low-Cost Plastic Optical Fiber Sensors for Gas Monitoring

This paper describes an approach to develop and deploy low-cost plastic optical fiber sensors suitable for measuring low concentrations of pollutants in the atmosphere. The sensors are designed by depositing onto the exposed core of a plastic fiber thin films of sensitive compounds via either plasma sputtering or via plasma-enhanced chemical vapor deposition (PECVD). The interaction between the...
