Updated PSSCs  An ability to receive signals from various sensors (temp., pressure, fuel level).  An ability to translate the sensor signals into meaningful data.  An ability to store data on external memory.  An ability to use a touch screen to send commands to the microcontroller to control the logging of data and to provide a user configurable display for the logging of data from multiple sensors.  An ability for the microcontroller to receive and execute commands to remotely enable, disable and control the sampling rate of multiple sensors.

Critical Design Constraints  Rugged and Durable Packaging, the product needs to last years.  Operating temperature from -30 C to 90 C  UART to interface with Atom Board.  32 K Flash would be sufficient, no less  At least six AtoD I/O  SPI interface for SD card  Low Power (Battery)

Pressure Sensors/ Transducers  Need to withstand extreme pressure range and temperatures. Has to have rugged construction.  We chose GE’s PTX/PMP 1260, because it has operating temp -40 F to 185 F  At the heart of PTX/PMP 1260 is an advanced, explosion proof, high stability pressure measurement element, micro- machined from single crystal silicon within.  Army/Navy (AN) fitting

Temperature Thermocouple  Again extreme operating conditions  Sufficient thermocouple length  Army/Navy (AN) fitting for safety reasons.  We chose - Omega kqss-116u-18  Perfect industrial thermocouple
