Description: This project is a low fuel warning module, designed to replace part of the function of an unobtainable industrial process controller used in the fuel system of the ViperJet Experimental-Amateur Built aircraft. It monitors the output of an optical liquid level sensor in the main fuel tank. If that sensor indicates low fuel for 20 seconds, this module pulls its EFIS_ALM output low and flashes a panel-mounted warning LED at 1.5Hz.
This project is intended for use in Experimental category aircraft only. Do NOT install it in a CAR Part 3 or FAR Part 23 certificated aircraft without FAA Field Approval.
