Detailed Description

The CSBuoy-DT consists of a buoy, internal CR206 datalogger with 900 MHz spread spectrum radio, an antenna, a sealed rechargeable battery, a 5 Watt solar panel, dissolved oxygen sensor, agitator brush (to generate water flow past the sensor), and a temperature probe. The onboard transceiver sent data to an onshore base station or the manager's office. The internal data logger was preprogrammed to measure the connected sensors.

The buoy requires a minimal amount of setup and can be deployed anywhere on the pond. This self-contained package can be easily moved from pond to pond.
