Circuit for Hall Effect Position Sensor
« on: December 13, 2016, 06:44:51 am »
Hey all. Looking for a couple of things regarding a hall effect sensor as a position sensor. First of all, does anybody have a clear description, tutorial, video on how a hall effect switch acts as a position sensor? Secondly, I want to demonstrate how an automotive throttle position sensor is used to provide the ECM position information using a circuit that can be built relatively easy. Any ideas?
Please do not confuse this with a camshaft/crankshaft position sensor. I am looking for a way to demonstrate how it replaces a potentiometer as a position sensor.

Formula student?
Penny and Giles are the bees knees for that kind of thing, eg. their TPS280 throttle position sensor:

Have a browse on their site you might find what you seek.

That was bang on the money. We use a WM830 in our highway trucks and that is what I am looking for.
Now I just need a laymans way of explaining how Hall Effect works as a position sensor and build a small demonstration of it actually working. Any thoughts?
