We wish to assemble a 12 volt system that uses these sensors, connected via CAN Bus, with the Aurduino performing monitoring, datalogging, and communications with a PC for data analysis. GPS Datalogging essential.
In summary, a system that is portable, attached to an automobile, that takes emissions data from the exhaust, combines it with time, speed, GPS data, and puts it in a format that can be retrieved, manipulated, reported on, etc. SQL Database?
