Arduino control

Another option depending on how accessable the top of your tanks are is a bulkhead mount ultrasound transducer.

The external capacitor sensing transducers used to be very expensive.

Oh there's also an internal resistive sensor, bulkhead mount. Basically a pressure sensitive strip inside a silicone or PTFE tube. Linear analog output based on fluid level. Nothing to jam or foul, even if paper or detritus gets stuck it won't change the overall pressure.

fly any chance on a parts break down and the code from the arduino?

you guys should looks at the esp8226 modules, uses the same ide as the arduino and has wifi built in.

for the tank level , there is a Arduino program that does not need to use probes, using capactive sensing i have found, and was then going to use a bluetooth module to send the information to the display

YOu might want to set the generator start voltage a bit higher.. No other comments other than "Good JOb".

Details on the fuel flow sensor?

I was thinking about putting one on the propane line. Hall effect, ultra sonic or microwave.

I have found a project on line that someone had done, and went from there.. here is a like to that https://open.library.ubc.ca/media/download/pdf/52966/1.0074464/1

as our motor home is older it has no engine electronics to get fuel flow or speed info off OBD port

Looks like they are popular toys. I started building my tank level sensor last spring. Too cheap to pay $200 for a factory version when I can do it for less than $20, beside, I enjoy the challenge.

Got started with programming but then my previous employer asked me to come back to work for a while. It's on hold.

Will probably start again when I retire again in a year or so.

Congratulations on a job well done!

How often does the genny fail to start after the three tries?
