Sensor applications for plant phenotyping can advance and strengthen crop breeding programs. One of the powerful sensing options is the automated sensor system, which can be customized and applied for plant science research. The system can provide high spatial and temporal resolution data to delineate crop interaction with weather changes in a diverse environment. Such a system can be integrated with the internet to enable the internet of things (IoT)-based sensor system development for real-time crop monitoring and management. In this study, the Raspberry Pi-based sensor (imaging) system was fabricated and integrated with a microclimate sensor to evaluate crop growth in a spring wheat breeding trial for automated phenotyping applications. Such an in-field sensor system will increase the reproducibility of measurements and improve the selection efficiency by investigating dynamic crop responses as well as identifying key growth stages (e.g., heading), assisting in the development of high-performing crop varieties. In the low-cost system developed here-in, a Raspberry Pi computer and multiple cameras (RGB and multispectral) were the main components. The system was programmed to automatically capture and manage the crop image data at user-defined time points throughout the season. The acquired images were suitable for extracting quantifiable plant traits, and the images were automatically processed through a Python script (an open-source programming language) to extract vegetation indices, representing crop growth and overall health. Ongoing efforts are conducted towards integrating the sensor system for real-time data monitoring via the internet that will allow plant breeders to monitor multiple trials for timely crop management and decision making.

AbstractThis article focuses on the production and dissemination of photographic images by serving US soldiers in Iraq who are photographing their experiences and posting them on the Internet. This form of visual communication – in real time and communal – is new in the representation of warfare; in earlier wars soldiers took photographs, but these were not immediately shared in the way websites can disseminate images globally. This digital generation of soldiers exist in a new relationship to their experience of war; they are now potential witnesses and sources within the documentation of events, not just the imaged actors – a blurring of roles that reflects the correlations of revolutions in military and media affairs. This photography documents the everyday experiences of the soldiers and its historical significance may reside less in the controversial or revelatory images but in more mundane documentation of the environments, activities and feelings of American soldiery at war.
