How the sensors need to get connected is explained in the manual but my question is how have users done this?
- wire the sensors up and keep all in the same rpi-case? - or
- use a breakout board, connect it there and put the breakout board in the rpi-case (it now does not close properly anymore) - or
- put the sensors in another housing and run a 4 wire cable back into the rpi-case - or ?
In the first 2 options probably the temperature readings will be distorted by the processor heat. Whats your experience there?
Can someone share pictures from the actual setup (not the schematics - they are already in the manual)
Thanks for info!
Until analogue inputs are supported, the only inputs I'm interested are temperature and switches. I have 3 of the DS18B20 temp sensors specified in the manual on a 3m extension cable. These (will when fitted in 2 weeks time) measure exhaust/mixing elbow temp, Alternator temp and seawater/cooling water IN temp. The switches (also on the extension cable) sense coolant flow stopped and bilge pump activated..
I assume that the pressure/humidity sensors would be happy in the Pi case but others will no doubt confirm.
