Project Overview

Instrumentation and analysis system for a aluminum-fuelled hydrogen-powered golf cart.

Primary goal: aid in very promising hydrogen-fuel technology codenamed “Alumoline”.

Sensors to monitor important hydrogen system readings.

Dashboard display similar to Toyota Prius and Nissan GT-R.

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
