In cooperation with the Sawyer Working Group, a new version of the culturally situated sensors is currently in development for deployment in rivers and lakes. These networks will hopefully provide an inexpensive means of constantly collecting data on contamination and pinpoint and eliminate sources of contamination. These sensor nodes are to have new sensors developed by Professor Sawyers team for detecting bacteria, but will build off of the platform developed previously. This project will hopefully proceed to a test deployment in Poestenkill and then potentially Lake George or the Hudson River In collaboration with Professor Chris Bystroff and Toby Michelena. It is our hope that we can get a version of this into the water by the end of the fall semester, although truthfully, it may not happen until early spring. Further deployments will follow in the spring. Once a successful deployment has been made, it is hoped that students at Albany High school can be involved by having them help develop a new generation of nodes for use at school or for deployment at one of the aforementioned locations.
While the GIS components should fit in with the work being done by Kathleen Tully. I, James Davis, am currently developing the physical nodes and software. The project breaks down into 5 parts: Communication, Power, Enclosure, Flow cell, and Sensors.
An Android application that connects to Arduinos and downloads data has been developed, with progress being made toward Arduino to Arduino communication (so that one need not wade into the middle of a lake or large river to collect data). Hopefully this additional functionality will be completed by 10/28.
Sensor nodes will be largely solar powered. The components for this have been delivered and a test setup was made to confirm viability. Assembly of the full prototype and testing has been handed of to former fellow Andrew Ellis of the Sawyer Working Group.
A buoy and anchor for the first prototype have been acquired by Toby Michelena, and starting 10/23 construction on the enclosure should begin.
A flow cell is slated to be built and tested, but the necessary components are still on order and may not arrive until 10/28.
The bacterial sensor is currently being upgraded by several generations of sensors to one developed by Dr. DaLi Shao that is more robust, sensitive and accurate. A new PCB has been designed, fabricated, and tested for the implementation of these sensors, and a second generation is currently under review.
Further sensors for turbidity and temperature are being tested as part of the system. And will be integrated before deployment.
