Dataset: Heron Island Sensor Float 5


A round 1.4m yellow buoy has been deployed in the Heron Island lagoon as part of the sensor network infrastructure at Heron Island in the southern Great Barrier Reef off Gladstone, Australia. \n \nThe buoy is configured as a sensor-float with a Campbell Scientific logger, a spread-spectrum radio for communicating with the on-reef wireless network, a GPS and initially a surface mounted (30cm under the water surface) thermistor. \n \nThe float is moored in the lagoon of Heron Island in around 3m of water and will be used to monitor the flow of water through the lagoon. It will be fitted with surface salinity and bottom depth and temperature in late 2008. \n \nThe unit will be serviced every six months and will be used in the future for attaching new sets of sensors. The buoy is re-locatable and the GPS data should be used to find the current location.\n The buoy is one of five re-locatable platforms in the lagoon at Heron Island onto which sensor will be located. The buoys initially have a Campbell Scientific loggers powered off two 5W solar panels, a Garmin GPS unit and one thermistor located at the base of the buoy around 30cm below the water line. The buoys use a Campbell Scientific spread-spectrum radio to talk back to the base station located on Heron Island.\n Power Supply \nBattery Backed (1 x 33Ahr AGM with Solar Regulator), 2 x 5W Solar Panel Supply. \n \nLogger Settings - \nPakbus Address - 175 \nLogger Setup as node (isRouter = False) \nCSDC7 comms board rate set at 34K \nSDC7 Neighbours range: 1-1, 150-150,130-130 \nSCD7 beacon = 21600 \n \n \nOver-Reef RF Network - \nRF411 attached to the CSIO port of the logger \n \nRadio Settings - \nActive Interface - Datalogger CSDC \nSDC Address 7 \nProtocol: Pakbus aware \nRadio Net Address - 0 \nHop Sequence - 0 \nPower mode - < 2mA 1 Second \nRetry level - Low\n
