“…1, 2) represents a simple general-purpose hardware/software framework for physically and functionally integrating commonly used oceanographic sensors, instruments, and peripheral devices. The concept of using microcontrollers not only to log data from disparate oceanographic sensors but to integrate sensors, instruments, and peripherals is not novel (e.g., Hosom et al 1995;Laney 2005;Plueddemann et al 1992), but unique elements of this approach include its specific design for a broad range of potential applications, its use of recent innovations in microcontroller technology, and the miniaturization that allows it to be potted into standard cable splices if desired. For many applications such a simple integrating solution may be preferable to the more traditional approach involving a custom datalogger or process controller inside a pressure housing, especially where weight, size, power consumption, or cost is an issue or where use at depth is not.…”

Sensors and instruments for basic oceanographic properties are becoming increasingly sophisticated, which both simplifies and complicates their use in field studies. This increased sophistication disproportionately affects smaller-scale observational efforts that are less likely to be well supported technically but which need to integrate instruments, sensors, and commonly needed peripheral devices in ways not envisioned by their manufacturers. A general-purpose hardware and software framework was developed around a widely used family of low-power microcontrollers to lessen the technical expertise and customization required to integrate sensors, instruments, and peripherals, and thus simplify such integration scenarios. Both the hardware and associated firmware development tools provide a range of features often required in such scenarios: serial data interfaces, analog inputs and outputs, logic lines and power-switching capability, nonvolatile storage of data and parameters for sampling or configuration, and serial communication interfaces to supervisory or telemetry systems. The microcontroller and additional components needed to implement this integration framework are small enough to encapsulate in standard cable splices, creating a small form factor ''smart cable'' that can be readily wired and programmed for a range of integration needs. An application programming library developed for this hardware provides skeleton code for functions commonly desired when integrating sensors, instruments, and peripherals. This minimizes the firmware programming expertise needed to apply this framework in many integration scenarios and thus streamlines the development of firmware for different field applications. Envisioned applications are in field programs where significant technical instrumentation expertise is unavailable or not cost effective.
