Our tugbout ( construct in 1951, nonetheless original engine, in day by day use ) needed an instrumentation improve. The boat additionally has 2 wheelhouses and a pair of mills, 2 chargers/inverters and shore connection.
i have mounted an Arduino Ethernet inside the engine room, used a corridor sensor to measure rpm of the engine, for now there are 6 ds18b20 in use, #7 may be hooked up shortly. furthermore the Arduino also steers the unique ( read: antique ) RPM tool inside the primary wheelhouse.
i'm sourcing the sensors to measure exhaust temperatures and oil/air stress (Honeywell has 'm).
in spite of sampling temperature on 6 factors, be counted rpm and steer analog meter, i am handiest using three ports at the Arduino and spent less than €one hundred twenty on hardware! The maximum steeply-priced components are the adapters to mount the sensors watertight into the cooling system.
To display this data i'm using steelseries gauges, designed through Gerrit Grunwald, locate all resources right .
i have tailored the radial demo page to my wishes and got very fascinating results.
