I am working with a small group of marine diesel enthusiasts on an open source Arduino engine monitoring system for engines that were built before electronic monitoring systems were stock.
We are considering using the DS18b20 temp sensor in several places to monitor raw water and the anti-freeze side of the engine. I have reviewed the specifications for DS18b20 and the temperatures are well within tolerance (nothing higher than 230 degrees). I've also reviewed
Here is the date sheet of ds18b20:www.componentschip.com/.../DS18B20.html
Assuming keeping the temperature within tolerance and the unit water-tight, is the DS18b20 likely to handle the vibrations it would experience mounted on a diesel?
There are thermocouples included in the monitoring system, like for the exhaust gas temperature and they have held up well so far. However they require extra hardware compared to the DS18b20. Also, the DS18b20 is more accurate and more of them can be accommodated on a stock Uno. We are planning on putting them at the following locations:
I don't think you'll have issues with vibrations, as this unit has no moving parts as far as I know.
you may have problems with custom water-proofing, though.
DS18b20 is also available as a weatherproof unit with cable (available on eBay, Sparkfun, Adafruit and more)
the unit is encased in a stainless steel enclosure and has a pretty rugged cable.
Did you go further with this I am doing a similar thing
