Hello there,
Long, long, time ago there was an article in Popular Electronics that had a project about an oil dipstick level sensor. The basic idea was to connect a line of resistors down the dipstick and test the resistance, and the resistance of the string had a correlation to the amount of oil left in the oil pan. The hot oil would change the resistance.
With today's SMD resistors this could be even simpler, or at least smaller and fit nicer on the dipstick. Also, it might work for automatic transmission fluid too.
The idea is to be able to test the oil level and/or transmission fluid WHILE THE CAR is being driven, not just at rest. That would be to prevent damage to any of the systems if the fluid got low unexpectedly.
Anyone ever try this, or any better ideas now that electronics has advanced so much since maybe the 1960's ?
This would be a good project for anyone that wants to try to make sure they dont run low on some fluid in the car while driving, which is when the damage occurs.
Thanks a bunch.
