rickerman:
I have interfaced a crank shaft sensor to an Arduino and a square wave. The VR sensor produces a sine wave as you say, but this generally only has 2 wires connected to it and not 3. You can use the sine wave also, but will probably want to add a schmitt trigger.You need to know how much current the sensor needs before connecting it directly to the Arduino as you can only provide so much current before damaging the Arduino. If that is not the correct datasheet can you even be sure that the sensor will run off 5V?
At the moment I am not sure if it is of the inductive type or hall effect. As I said the only thing described in manuals is that it is a magnetic pickup sensor on a 60 tooth gear wheel. I tought magnetic pick up is the same as an inductive proximity sensor and is different than the hall effect..
The datasheet I posted previous is from an electrical diagram I received by mail last week from SuperFlow. However, in the manual deliverd by the dyno this one is not mentioned.
Really shit I am not sure which sensor it is.. Also stuck what I have to do now..
rickerman:
Is this sensor not in use by the dyno? The 10k resistor is to make sure that the arduino does not interfere too much with the signal so that the dyno can still dyno can still get a decent signal from the sensor.
No this is a spare one. Exactly the same if the one which is mounted on the dyno
