Hi all,
I was wondering if someone could guide me in the right direction building my boat engine monitoring!
My idea is basically that I want to see the engine hours, RPM, tank level to start with in an web interface (SignalK) thru my Raspberry Pi or any other device.
I have an old Volvo Penta 2030 engine. From the physical dashboard I can see tank level, RPM, engine hours.
The goal is keep the existing official/original sensors and get the data into SignalK.
I could not find details on the require hardware to get all those data (tank level, RPM, engine hours).
Could I get the data directly to the RaspberryPI or would I need a separate device like an Arduino?
My guess is that all the sensors are Analog and 12V!? Therefor I would need a analog-to-digital converter like an MCP3008, but how channel and bit do I need?
I have found some ready to go hardware that translate analogue signals to an NMEA2000. However it is very expensive and I don't need NMEA2000 conversion as JSON input is fine for SignalK.
I am new to openplotter, so I apologize if this has been answer. But learning everyday!
Thanks
