DESAIN SISTEM MONITORING FLOWMETER KOMUNIKASI RS 232 MENGGUNAKAN SOFTWARE NODE-RED PADA FUEL CELL ELECTRIC VEHICLE

One of the applications fuel cells is Fuel Cell Electric Vehicles (FCEV). FCEV more efficient and produces no carbon emissions than conventional internal combustion engine vehicles. emitting only water vapor warm air. This research hoped will provide new knowledge regarding monitoring system for hydrogen output in FCEVs using Node-RED software application, as well flowmeters with RS 232 output. The design this serial flowmeter was carried out cell laboratory, Energy Conversion Conservation Research Center (PRKKE). by direct observation laboratory where electric cars were studied, collected data directly laboratory. flow begins providing a timestamp every 10 seconds when operated, debugging to determine how results trials failures occur. When tenth second from enters Moxa Nport device server. combines NPort 5230 server, battery supply, RS232 communication, several electronic circuits. testing experiment on obtained 1.38 speed 1.46 l/min.
