Hall Effect/Reed Sensors
What's a good sensor I could use? Preferably something that connects via PWM.

Re: Hall Effect/Reed Sensors
We are successfully using the US1881 Hall Latch. I got the units at Spark Fun and built a circuit/PCB around it. We tested it this week with a wheel spinning upwards of 5400 RPMs (FP on an AM gearbox). We put some 1/8th inch rare earth magnets on an idler sprocket. The us1881 responds well with the tiny magnets up to about 1/2 inch away.
US1881: http://www.sparkfun.com/products/9312 Magnets we are using - small but work well with the chip: http://www.sparkfun.com/products/8644 Thread discussing the sensor: http://www.chiefdelphi.com/forums/sh...63#post1114963 Feel free to let me know if you need any help with it |
