Hi,
I'm trying to get info on the best way to add a sensor to my truck's engine for determining absolute position of the crankshaft while the engine is running. The sensor would be used for tuning purposes, as well as connecting to a small laptop for data logging. Through the PC, I planned on taking a feed from the tachometer signal to determine the ignition timing from inside the truck as well. No real practical application, just a fun project for me.
My needs are fairly simple: It should be able to measure 360=B0 or better (such as 720=B0 or 1440=B0) as well as be durable enough to handle the heat under the hood and normal amounts of dirt from the road.
I'm assuming a magnetic / hall effect sensor would be best, but where do I get something with the accuracy I need?
Thanks,
