Hi all,
How to i can analysis the RPM sensor signal (effect hall) with an microcontroller and show it. Please tell me method of proccess data.
Thanks great

Do you suppose three successive posts will yield triple the number of responses?

Just signal-condition the Hall effect RPM sensor to CMOS logic levels and feed it to a digital input bit on a CMOS microcontroller. Then roll a little code to measure the time between pulses and send it back out to whatever display suits your fancy. If you don't have a fancy, more information is necessary before we can tell you a "method to process data."

Thaks, you're right.
after measure the time between pulses, What should I do?

Do you want to do this with logic gates and maybe some seven segment displays or using a microprocessor?

What work have you done so far? You need to choose a processor that you want to use. Then think about the sensing circuitry, Hop @hevans1944 gave you an idea in his post above. Once you have done this we can fill in the gaps for you if you have forgotten anything.

You could have ago at drawing a circuit diagram unless you already have one,there are plenty of free circuit diagram packages out there. I can recommend DIP-TRACE but you may already have one. You will need to also supply details of the sensor and any pictures of the setup you have. Additional information like max RPM and any power requirements like current consumption and power supply voltages.

Tell us more about your project, your introduction was very short.

Thanks
Adam
