Bottom Water Temperature and Pressure Sensor with Real-time Readout

Monitors that are currently used to periodically record bottom water temperatures cannot be read by the lobstermen who use them. In addition, current monitors make no provision for recording changes in depth if they are redeployed in a different location. The specific aim of this proposal is to develop a sensor that will measure water temperature and pressure hourly and will be readable by a radio frequency (RF) signal from a standard hand-held computer. Data will be immediately available for graphical display by the user. The sensor will be designed for minimal power consumption, to provide extended batter life, and will be recharged by RF induction, allowing the unit to be completely and permanently sealed.
