Re: The Hall Effect sensor wiring?

I found out what I was doing wrong when I was testing the Hall Effect gear tooth sensor thanks to these forms. I was not putting enough load on the circuit with just the oscilloscope. The data sheet showed that by placing a 500 ohm resister (RL) between the supply and the output, I was able to get a nice square wave and a steady frequency reading. I had to set up a chain ring in the drill press, because just waving a piece of metal past it gave very poor results.
